MuniVest Fund II, Inc.

The Benefits and Risks of Leveraging

MuniVest Fund II, Inc. utilizes leveraging to seek to enhance the yield and net
asset value of its Common Stock. However, these objectives cannot be achieved in
all interest rate environments. To leverage, the Fund issues Preferred Stock,
which pays dividends at prevailing short-term interest rates, and invests the
proceeds in long-term municipal bonds. The interest earned on these investments,
net of dividends to Preferred Stock, is paid to Common Stock shareholders in the
form of dividends, and the value of these portfolio holdings is reflected in the
per share net asset value of the Fund's Common Stock. However, in order to
benefit Common Stock shareholders, the yield curve must be positively sloped;
that is, short-term interest rates must be lower than long-term interest rates.
At the same time, a period of generally declining interest rates will benefit
Common Stock shareholders. If either of these conditions change, then the risks
of leveraging will begin to outweigh the benefits.

To illustrate these concepts, assume a fund's Common Stock capitalization of
$100 million and the issuance of Preferred Stock for an additional $50 million,
creating a total value of $150 million available for investment in long-term
municipal bonds. If prevailing short-term interest rates are approximately 3%
and long-term interest rates are approximately 6%, the yield curve has a
strongly positive slope. The fund pays dividends on the $50 million of Preferred
Stock based on the lower short-term interest rates. At the same time, the fund's
total portfolio of $150 million earns the income based on long-term interest
rates.

In this case, the dividends paid to Preferred Stock shareholders are
significantly lower than the income earned on the fund's long-term investments,
and therefore the Common Stock shareholders are the beneficiaries of the
incremental yield. However, if short-term interest rates rise, narrowing the
differential between short-term and long-term interest rates, the incremental
yield pickup on the Common Stock will be reduced or eliminated completely. At
the same time, the market value on the fund's Common Stock (that is, its price
as listed on the New York Stock Exchange) may, as a result, decline.
Furthermore, if long-term interest rates rise, the Common Stock's net asset
value will reflect the full decline in the price of the portfolio's investments,
since the value of the fund's Preferred Stock does not fluctuate. In addition to
the decline in net asset value, the market value of the fund's Common Stock may
also decline.

As a part of its investment strategy, the Fund may invest in certain securities
whose potential income return is inversely related to changes in a floating
interest rate ("inverse floaters"). In general, income on inverse floaters will
decrease when short-term interest rates increase and increase when short-term
interest rates decrease. Investments in inverse floaters may be characterized as
derivative securities and may subject the Fund to the risks of reduced or
eliminated interest payments and losses of invested principal. In addition,
inverse floaters have the effect of providing investment leverage and, as a
result, the market value of such securities will generally be more volatile than
that of fixed-rate, tax-exempt securities. To the extent the Fund invests in
inverse floaters, the market value of the Fund's portfolio and the net asset
value of the Fund's shares may also be more volatile than if the Fund did not
invest in such securities. As of April 30, 2005, the percentage of the Fund's
total net assets invested in inverse floaters was 10.08%, before the deduction
of Preferred Stock.

Swap Agreements

The Fund may invest in swap agreements, which are over-the-counter contracts in
which one party agrees to make periodic payments based on the change in market
value of a specified bond, basket of bonds, or index in return for periodic
payments based on a fixed or variable interest rate or the change in market
value of a different bond, basket of bonds or index. Swap agreements may be used
to obtain exposure to a bond or market without owning or taking physical custody
of securities. Swap agreements involve the risk that the party with whom the
Fund has entered into the swap will default on its obligation to pay the Fund
and the risk that the Fund will not be able to meet its obligations to pay the
other party to the agreement.

A Letter From the President

Dear Shareholder

Financial markets faced a number of crosscurrents over the past several months,
but most major benchmarks managed to post positive returns for the annual and
semi-annual reporting periods ended April 30, 2005:

After expanding at an annualized rate of 4.4% in 2004, U.S. gross domestic
product growth for the first quarter of 2005 came in at an estimated 3.1%
(although that figure was later revised upward to 3.5%). Nevertheless, the
Federal Reserve Board continued increasing interest rates at a measured pace to
combat emergent inflation. The most recent hike came on May 3, and brought the
federal funds rate to 3%. Recently, signs of inflation have taken the form of
rising business costs and increasing consumer prices, particularly in the areas
of gasoline, healthcare, housing and education.

U.S. equities ended 2004 in a strong rally, but stumbled into negative territory
in 2005. The market weakness was largely fueled by the potential for slowing
economic and corporate earnings growth, renewed energy price concerns and a lack
of investor conviction. On the positive side, certain sectors of the market have
been performing well (particularly energy) and corporate transactions, such as
mergers and acquisitions, stock buy-backs and dividend payouts, have all
increased. International equities, especially in Asia, have benefited from
higher economic growth rates.

In the bond market, we witnessed a yield curve flattening trend over the past
several months as short-term yields increased and longer-term interest rates
remained more stable or fell. At the end of April 2005, the two-year Treasury
note yielded 3.66% and the 10-year Treasury note yielded 4.21%, a difference of
55 basis points (.55%). This compared to a spread of 149 basis points six months
earlier and 222 basis points 12 months ago.

Looking ahead, the environment is likely to be a challenging one for investors.
With this in mind, we encourage you to meet with your financial advisor to
review your goals and asset allocation and to rebalance your portfolio, as
necessary, to ensure it remains aligned with your objectives and risk tolerance.
As always, we thank you for trusting Merrill Lynch Investment Managers with your
investment assets, and we look forward to serving you in the months and years
ahead.

                                Sincerely,


                                /s/ Robert C. Doll, Jr.

                                Robert C. Doll, Jr.
                                President and Director

A Discussion With Your Fund's Portfolio Manager

      The Fund outperformed its comparable Lipper category average for the
period, benefiting largely from our exposure to the higher-yielding portion of
the municipal market.

Describe the recent market environment relative to municipal bonds.

Amid significant volatility, long-term bond yields moved lower over the past six
months as shorter-term yields increased. For all of 2004, real gross domestic
product (GDP) grew at an annualized rate of 4.4%, well ahead of 2003's annual
rate of 3%. An advanced estimate of first quarter 2005 GDP came in at an
unexpectedly low 3.1%, although that figure was later revised upward to 3.5%.

It appeared that continued economic improvements were generally disregarded as
investors focused on inflationary trends, currency-related demand for long-term
U.S. securities, and interest rate action on the part of the Federal Reserve
Board (the Fed). During the past six months, 30-year Treasury bond yields
declined 28 basis points (.28%) to 4.51%, while 10-year Treasury note yields
rose 16 basis points to 4.21%. The Fed, in the meantime, continued to raise
short-term interest rates at each of its meetings throughout the period, and
most recently increased the federal funds rate from 2.75% to 3% on May 3. As
short-term interest rates increased while longer-term interest rates fell, the
yield curve continued to flatten.

In the tax-exempt market, yields on 30-year revenue bonds, as measured by the
Bond Buyer Revenue Bond Index, fell 14 basis points to 4.83% over the six-month
period. According to Municipal Market Data, yields on AAA-rated issues maturing
in 30 years declined 23 basis points to 4.37%, while AAA-rated bonds maturing in
10 years saw their yields rise 17 basis points to 3.57% during the six-month
period.

Over the past six months, more than $186 billion in tax-exempt bonds was
underwritten, an increase of 7.5% versus the same period a year earlier.
Issuance so far in 2005 has been boosted by a 32% increase in refunding issues
as municipalities sought to refinance existing higher-coupon debt. These
refunding issues have been heavily weighted in the 10-year - 20-year maturity
range to lower the overall interest cost of the refunding issue. This
concentration has put pressure on intermediate tax-exempt bond yields while
supporting longer-term bond prices.

Investor demand for municipal product remained generally positive during the
period. Investment Company Institute statistics indicate that, year-to-date
through March 31, 2005, net new cash flows into long-term municipal bond funds
exceeded $1.3 billion. This represented a significant improvement from the $516
million seen during the same period in 2004. However, AMG Data Services reports
that recent weekly figures for the month of April have shown a modest reversal
in the positive flows seen in the first three months of the year. Still,
throughout much of the past six months, high yield tax-exempt bond funds
experienced positive net cash flows. During the last week of April, these lower
rated/non-rated bond funds received more than $110 million in inflows. The need
to invest these ongoing cash flows has led to strong demand for lower-rated
issues and a resultant narrowing of credit spreads.

Looking ahead, we would expect the long-term municipal market to perform at
least as well as the U.S. Treasury market. The tax-exempt market's technical
position remains favorable. The 30-day visible supply of new underwritings at
the end of April stood at approximately $6.3 billion, slightly below its current
30-day moving average. In addition, it is likely that the increase in issuance
seen in recent months has borrowed from supply expected to be issued later in
the year. The refunding deals that inflated this six-month period's supply are
unlikely to be repeated later in the year. Tax-exempt bonds' attractive yield
ratios versus taxable securities should continue to attract both traditional and
nontraditional investors, especially if new municipal bond issuance remains
modest.

How did the Fund perform during the period?

For the six-month period ended April 30, 2005, the Common Stock of MuniVest Fund
II, Inc. had net annualized yields of 7.26% and 7.15%, based on a period-end per
share net asset value of $15.34 and a per share market price of $15.57,
respectively, and $.552 per share income dividends. Over the same period, the
total investment return on the Fund's Common Stock was +4.57%, based on a change
in per share net asset value from $15.21 to $15.34, and assuming reinvestment of
all distributions.

The Fund's total return, based on net asset value, outpaced the +3.83% average
return of the Lipper General Municipal Debt Funds (Leveraged) category for the
six-month period. (Funds in this Lipper category invest primarily in municipal


4                MUNIVEST FUND II, INC.         APRIL 30, 2005


debt issues rated in the top four credit-rating categories. These funds can be
leveraged via use of debt, preferred equity and/or reverse repurchase
agreements.) The Fund's outperformance can be attributed to its above-average
dividend yield, the continued strong performance of its lower-rated bond
holdings and positive security selection. The strong demand for high-yield
municipal securities (bonds rated BBB and below or non-rated) has driven the
prices on these bonds significantly higher. Fund performance benefited
accordingly, given our considerable exposure to these lower-rated,
higher-yielding credits. Also contributing to performance were our holdings in
California municipal debt. As investors perceived an improvement in the state's
creditworthiness, California bonds gained in value, benefiting the Fund's
results during the past six months.

For a description of the Fund's total investment return based on a change in the
per share market value of the Fund's Common Stock (as measured by the trading
price of the Fund's shares on the New York Stock Exchange), and assuming
reinvestment of dividends, please refer to the Financial Highlights section of
this report. As a closed-end fund, the Fund's shares may trade in the secondary
market at a premium or discount to the Fund's net asset value. As a result,
total investment returns based on changes in the market value of the Fund's
Common Stock can vary significantly from total investment returns based on
changes in the Fund's net asset value.

What changes were made to the portfolio during the period?

As mentioned earlier, the Fund's performance benefited from our positions in
California municipal debt. However, as the period progressed and yields on these
securities narrowed relative to other investments of comparable maturity, we
reduced our position to capitalize on the market appreciation. With the proceeds
from these sales, we invested primarily in New York credits, particularly New
York City and New York City Water revenue bonds. Following a significant amount
of new issuance, New York bonds had become attractively priced compared to
historical levels. In fact, at times during the period, New York City bonds were
offering more than 100% of the yield of comparable taxable U.S. Treasury bonds.

In recent months, we began to adopt a less defensive portfolio positioning. A
combination of factors -- including the Fed's continued program of short-term
interest rate increases, moderating economic growth expectations and declines in
leading economic indicators -- led us to believe that the potential for
significant interest rate increases later in 2005 and into 2006 was less than
previously anticipated. Thus, we sought to take advantage of periods of price
volatility by adding to our positions in bonds with greater sensitivity to
changes in interest rates. To generate funds for these purchases, we sold
pre-refunded bonds with eight-year - 10-year maturity dates, enabling us to lock
in the significant market appreciation these bonds have enjoyed while also
moving closer to our desired neutral portfolio positioning.

For the six-month period ended April 30, 2005, the Fund's Auction Market
Preferred Stock (AMPS) had average yields of 1.64% for Series A, 1.88% for
Series B, 1.77% for Series C and 1.98% for Series D. At this point in the Fed's
monetary tightening cycle, interest rate increases are having a material impact
on the Fund's borrowing costs. The Fed raised the short-term interest rate
target 100 basis points during the six-month period. Still, the tax-exempt yield
curve remained relatively steep and continued to generate an income benefit to
the holders of Common Stock from the leveraging of Preferred Stock. However,
should the spread between short-term and long-term interest rates narrow, the
benefits of leveraging will decline and, as a result, reduce the yield on the
Fund's Common Stock. At the end of the period, the Fund's leverage amount, due
to AMPS, was 36.32% of total net assets. (For a more complete explanation of the
benefits and risks of leveraging, see page 2 of this report to shareholders.)

How would you characterize the Fund's position at the close of the period?

We ended the period in transition toward a more neutral market stance. We are
monitoring economic and market conditions and would need to see additional
evidence of slowing economic activity or financial stress -- such as the recent
credit-rating downgrades of General Motors Corp. and Ford Motor Co. -- before
enacting a more aggressive market strategy. In the meantime, we intend to
maintain the portfolio's fully invested stance in order to enhance investment
income and allow the Fund to continue to seek an above-average dividend yield.

Notes to Financial Statements

1. Significant Accounting Policies:

MuniVest Fund II, Inc. (the "Fund") is registered under the Investment Company
Act of 1940, as amended, as a non-diversified, closed-end management investment
company. The Fund's financial statements are prepared in conformity with U.S.
generally accepted accounting principles, which may require the use of
management accruals and estimates. Actual results may differ from these
estimates. These unaudited financial statements reflect all adjustments, which
are, in the opinion of management, necessary to present a fair statement of the
results for the interim period. All such adjustments are of a normal, recurring
nature. The Fund determines and makes available for publication the net asset
value of its Common Stock on a daily basis. The Fund's Common Stock is listed on
the New York Stock Exchange under the symbol MVT. The following is a summary of
significant accounting policies followed by the Fund.

(a) Valuation of investments -- Municipal bonds are traded primarily in the
over-the-counter ("OTC") markets and are valued at the last available bid price
in the OTC market or on the basis of values as obtained by a pricing service.
Pricing services use valuation matrixes that incorporate both dealer-supplied
valuations and valuation models. The procedures of the pricing service and its
valuations are reviewed by the officers of the Fund under the general direction
of the Board of Directors. Such valuations and procedures are reviewed
periodically by the Board of Directors of the Fund. Financial futures contracts
and options thereon, which are traded on exchanges, are valued at their closing
prices as of the close of such exchanges. Options written or purchased are
valued at the last sale price in the case of exchange-traded options. In the
case of options traded in the OTC market, valuation is the last asked price
(options written) or the last bid price (options purchased). Swap agreements are
valued by quoted fair values received daily by the Fund's pricing service.
Short-term investments with a remaining maturity of 60 days or less are valued
at amortized cost, which approximates market value, under which method the
investment is valued at cost and any premium or discount is amortized on a
straight line basis to maturity. Investments in open-end investment companies
are valued at their net asset value each business day. Securities and other
assets for which market quotations are not readily available are valued at fair
value as determined in good faith by or under the direction of the Board of
Directors of the Fund.

(b) Derivative financial instruments -- The Fund may engage in various portfolio
investment strategies both to increase the return of the Fund and to hedge, or
protect, its exposure to interest rate movements and movements in the securities
markets. Losses may arise due to changes in the value of the contract or if the
counterparty does not perform under the contract.

o     Financial futures contracts -- The Fund may purchase or sell financial
      futures contracts and options on such futures contracts. Futures contracts
      are contracts for delayed delivery of securities at a specific future date
      and at a specific price or yield. Upon entering into a contract, the Fund
      deposits and maintains as collateral such initial margin as required by
      the exchange on which the transaction is effected. Pursuant to the
      contract, the Fund agrees to receive from or pay to the broker an amount
      of cash equal to the daily fluctuation in value of the contract. Such
      receipts or payments are known as variation margin and are recorded by the
      Fund as unrealized gains or losses. When the contract is closed, the Fund
      records a realized gain or loss equal to the difference between the value
      of the contract at the time it was opened and the value at the time it was
      closed.

o     Options -- The Fund may write covered call options and purchase put
      options. When the Fund writes an option, an amount equal to the premium
      received by the Fund is reflected as an asset and an equivalent liability.
      The amount of the liability is subsequently marked-to-market to reflect
      the current market value of the option written. When a security is
      purchased or sold through an exercise of an option, the related premium
      paid (or received) is added to (or deducted from) the basis of the
      security acquired or deducted from (or added to) the proceeds of the
      security sold. When an option expires (or the Fund enters into a closing
      transaction), the Fund realizes a gain or loss on the option to the extent
      of the premiums received or paid (or gain or loss to the extent the cost
      of the closing transaction exceeds the premium paid or received).

      Written and purchased options are non-income producing investments.


18               MUNIVEST FUND II, INC.         APRIL 30, 2005


Notes to Financial Statements (continued)

o     Forward interest rate swaps -- The Fund may enter into forward interest
      rate swaps. In a forward interest rate swap, the Fund and the counterparty
      agree to make periodic net payments on a specified notional contract
      amount, commencing on a specified future effective date, unless terminated
      earlier. When the agreement is closed, the Fund records a realized gain or
      loss in an amount equal to the value of the agreement.

(c) Income taxes -- It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no federal income tax provision is required.

(d) Security transactions and investment income -- Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Realized gains and losses on security transactions are determined on the
identified cost basis. Dividend income is recorded on the ex-dividend dates.
Interest income is recognized on the accrual basis. The Fund amortizes all
premiums and discounts on debt securities.

(e) Dividends and distributions -- Dividends from net investment income are
declared and paid monthly. Distributions of capital gains are recorded on the
ex-dividend dates.

(f) Offering costs -- Direct expenses relating to the public offering of the
Fund's Preferred Stock were charged to capital at the time of issuance of the
shares.

2. Investment Advisory Agreement and Transactions with Affiliates:

The Fund has entered into an Investment Advisory Agreement with Fund Asset
Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc.
("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML
& Co."), which is the limited partner.

FAM is responsible for the management of the Fund's portfolio and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the Fund. For such services, the Fund pays a monthly fee at
an annual rate of .50% of the Fund's average weekly net assets, including
proceeds from the issuance of Preferred Stock. The Investment Adviser has agreed
to reimburse its management fee by the amount of management fees the Fund pays
to FAM indirectly through its investment in Merrill Lynch Institutional
Tax-Exempt Fund. For the six months ended April 30, 2005, FAM reimbursed the
Fund in the amount of $2,049.

For the six months ended April 30, 2005, Merrill Lynch, Pierce, Fenner & Smith
Incorporated ("MLPF&S"), an affiliate of FAM, received underwriting fees of
$400,000 in connection with the issuance of the Fund's Preferred Stock.

In addition, MLPF&S received $3,105 in commissions on the execution of portfolio
security transactions for the Fund for the six months ended April 30, 2005.

For the six months ended April 30, 2005, the Fund reimbursed FAM $4,765 for
certain accounting services.

Certain officers and/or directors of the Fund are officers and/or directors of
FAM, PSI, and/or ML & Co.

3. Investments:

Purchases and sales of investments, excluding short-term securities, for the six
months ended April 30, 2005 were $210,535,648 and $172,785,778, respectively.

4. Stock Transactions:

The Fund is authorized to issue 200,000,000 shares of stock, including Preferred
Stock, par value $.10 per share, all of which were initially classified as
Common Stock. The Board of Directors is authorized, however, to reclassify any
unissued shares of stock without approval of holders of Common Stock.

Dividend Policy

The Fund's dividend policy is to distribute all or a portion of its net
investment income to its shareholders on a monthly basis. In order to provide
shareholders with a more stable level of dividend distributions, the Fund may at
times pay out less than the entire amount of net investment income earned in any
particular month and may at times in any particular month pay out such
accumulated but undistributed income in addition to net investment income earned
in that month. As a result, the dividends paid by the Fund for any particular
month may be more or less than the amount of net investment income earned by the
Fund during such month. The Fund's current accumulated but undistributed net
investment income, if any, is disclosed in the Statement of Net Assets, which
comprises part of the financial information included in this report.

MuniVest Fund II, Inc. seeks to provide shareholders with as high a level of
current income exempt from federal income taxes as is consistent with its
investment policies and prudent investment management by investing primarily in
a portfolio of long-term, investment grade municipal obligations the interest on
which, in the opinion of bond counsel to the issuer, is exempt from federal
income taxes.

This report, including the financial information herein, is transmitted to
shareholders of MuniVest Fund II, Inc. for their information. It is not a
prospectus. Past performance results shown in this report should not be
considered a representation of future performance. The Fund has leveraged its
Common Stock and intends to remain leveraged by issuing Preferred Stock to
provide the Common Stock shareholders with a potentially higher rate of return.
Leverage creates risks for Common Stock shareholders, including the likelihood
of greater volatility of net asset value and market price of shares of the
Common Stock, and the risk that fluctuations in the short-term dividend rates of
the Preferred Stock may affect the yield to Common Stock shareholders.
Statements and other information herein are as dated and are subject to change.

to vote proxies relating to portfolio securities is available (1) without
