DEAR SHAREHOLDER

The Municipal Market Environment
During the six-month period ended June 30, 2001, among considerable weekly
volatility, long-term fixed-income bond yields generally moved higher. So far in
2001, investors have generally focused on the actions taken by the Federal
Reserve Board to reverse the ongoing US economic slowdown. US economic growth
fell into the 1%-2% range in 2001 after expanding at more than 5% during the
first half of 2000. In mid-December 2000, the Federal Reserve Board announced
that economic conditions warranted the cessation of the series of short-term
interest rate increases initiated in February 2000. Citing declining consumer
confidence and weakening industrial production, the Federal Reserve Board at
each of the meetings in January, February and March of this year lowered short-
term interest rates in an effort to promote stronger US economic growth. Given
continued weak equity markets, investors focused on the declining supply of US
Treasury securities and forecasts of sizeable Federal budget surpluses. This
positive economic environment fostered a significant decline in US Treasury bond
yields. By late March 2001, US Treasury bond yields declined approximately 20
basis points (0.20%) to 5.25%.

Despite additional actions by the Federal Reserve Board in April, May and June,
fixed-income securities were unable to maintain their earlier market gains.
Recovering US stock markets, especially the NASDAQ, caused many investors to
reallocate assets out of US Treasury securities to equities. Additionally, many
investors believed that the 275 basis point decline in short-term interest rates
engineered by the Federal Reserve Board over the last six months would
eventually rekindle a strong US economy with concomitant inflationary pressures.
In recent months, recovering equity markets, renewed inflationary fears, and the
expectation that the US economy will resume strong growth in late 2001 put
consistent pressures on fixed-income issues. By the end of June 2001, long-term
US Treasury bond yields rose to 5.75%, an increase of approximately 30 basis
points over the last six months.

During the last six months, tax-exempt bond yields also reacted to the Federal
Reserve Board actions and equity market volatility. However, this reaction was
muted in both intensity and degree. In early 2001, municipal bond yields traded
in a narrow range supported by a strong US Treasury market and continued
investor demand. As it became apparent that any proposed changes in the Federal
tax system were unlikely to have any immediate, material impact on existing
Federal tax brackets, tax-exempt bond yields responded by moving higher in early
2001. By late March 2001, long-term uninsured revenue bond yields, as measured
by the Bond Buyer Revenue Bond Index, approached 5.40%, a decline of
approximately 10 basis points from the end of December 2000. Similar to the US
Treasury market, tax-exempt bond yields were pushed higher during the remainder
of the period by equity market improvement in April, as well as the possibility
that the Federal Reserve Board was close to the end of its current interest rate
easing cycle. At the end of June 2001, long-term municipal bond yields rose to
approximately 5.50%, although during the past six months, they rose
approximately five basis points.

The recent relative outperformance of the tax-exempt bond market was
particularly impressive given the dramatic increase in long-term municipal bond
issuance during the June 2001 quarter. Historically, low municipal bond yields
have continued to allow municipalities to refund outstanding, high-couponed
debt. Also, as yields rose in early April, tax-exempt issuers rushed to issue
new financing, fearing higher yields in the coming months. During the past six
months, almost $135 billion in long-term tax-exempt bonds was issued, an
increase of more than 40% compared to the same period a year ago. During the
three-month period ended June 30, 2001, tax-exempt bond issuance was
particularly heavy, with more than $75 billion in long-term municipal bonds
underwritten, an increase of more than 45% compared to the same three-month
period a year ago.

Historically, June has been a period of weak investor demand for tax-exempt
products as investors are often forced to liquidate bond positions to meet
Federal and state tax payments. In recent months, there was no appreciable
selling by retail accounts. It has been noted that, thus far in 2001, new net
cash inflows into municipal bond mutual funds have reached $4 billion compared
to new net cash outflows of more than $13 billion for the same period a year
ago. This suggests that the positive technical structure of the municipal market
has remained intact. Also, the months of June and July tend to be periods of
strong retail demand in response to the larger-coupon income payments and
proceeds from bond maturities these months generate. Additionally, short-term
tax-exempt interest rates are poised to move lower. Seasonal tax pressures have
kept short-term municipal rates artificially high, although not as high as in
recent years. As these pressures abate, short-term interest rates are likely to
decline below 3%. As short-term interest rates decline, investors have tended to
extend maturities to take advantage of the steep municipal yield curve. We
believe all of these factors should enhance the tax-exempt market's technical
position in the coming months.

Looking forward, the municipal market's direction appears uncertain. Should the
US economy materially weaken into late summer, the Federal Reserve Board may be
forced to ease monetary policy to a greater extent than investors currently
expect. The prospect of two or three additional interest rate easings may push
fixed-income bond yields, including municipal bond yields, lower. However,
should the cumulative 275 basis point reduction in short-term interest rates by
the Federal Reserve Board and the economic stimulus expected to be produced by
recent Federal tax reform combine to restore consumer confidence and economic
activity, tax-exempt bond yields may not decline further. Given the strong
technical position of the municipal bond market, we believe the tax-exempt
market is poised to continue to outperform its taxable counterpart in the coming
months.

Fiscal Year in Review
Insured Portfolio
For the year ended June 30, 2001, Insured Portfolio's Class A, Class B, Class C
and Class D Shares had total returns of +10.01%, +9.04%, +8.99% and +9.74%,
respectively. (Fund results do not reflect sales charges and would be lower if
sales charges were included.) In managing the Insured Portfolio, we seek to
provide a balanced performance, focusing on achieving a high current yield with
a competitive total return. While maintaining very low cash reserves for most of
the fiscal year ended June 30, 2001, we concentrated on purchasing premium
coupons in the 10-year - 20-year range. The 15-year portion of the municipal
yield curve provided above-average risk-adjusted returns, while capturing
greater than 90% of the yield further out on the curve. Our strategy enabled the
Portfolio to maintain a very competitive yield with a more neutral interest rate
position. In addition, we increased the Portfolio's exposure to insured inverse
floater securities. With the Federal Reserve Board lowering short-term interest
rates, investments in both inverse floaters and intermediate maturity bonds
enabled the Portfolio to achieve a high current yield with competitive total
returns.

The municipal market environment for the 12-month period ended June 30, 2001
required us to manage the portfolio in two distinct rate trends, each lasting
approximately six months. At mid-June 2000, 10-year Treasury securities yielded
6%. Our strategy at that time was to be more aggressive with the Portfolio, as
we owned longer duration, discounted securities that offered potential for
capital appreciation as interest rates later declined. While the Portfolio was
fully invested at this stage, performance resulted more from a generous accrual
and current yield than an overly aggressive market position. We stressed higher
credit quality in the middle of last year, and therefore avoided any negative
situations involving declining credit concerns. As 2000 ended, interest rates
declined (nearly 5% for 10-year US Treasury bonds) and the Portfolio assumed a
more defensive structure. Longer-maturity holdings were sold with proceeds
reinvested in serial maturities or prerefunded bonds, which can offer more price
protection should interest rates start to rise again.

Since the beginning of 2001, interest rates trended upward and our defensive
strategy helped cushion the decline in net asset valuation. Cash equivalent
reserves were kept low in order to maintain competitive returns, and our
exposure to inverse floater product was increased to take advantage of an
extremely favorable technical position in the short end of the tax-exempt
market, resulting from aggressive Federal Reserve Board easings. At mid-year
2001, interest rates were in the center of the recent fiscal year trading range.

Merrill Lynch Municipal Bond Fund, Inc., June 30, 2001

We expect our strategy going forward to be to remain focused on achieving
performance results through a more defensive structure, with more attention to
the current yield portion of the total return equation. We also expect to
continue to maintain a higher degree of credit quality since we believe that
focusing on assets in the top rating categories should shield the Portfolio from
most credit deterioration associated with the current economic slowdown.

National Portfolio
During the fiscal year ended June 30, 2001, National Portfolio's Class A, Class
B, Class C and Class D Shares had total returns of +10.32%, +9.49%, +9.33% and
+10.04%, respectively, by emphasizing current yield and credit quality. (Fund
results do not reflect sales charges and would be lower if sales charges were
included.) The period was characterized by reduced price volatility that
provided few real trading opportunities, with a slight trend toward higher
municipal yields. We generally maintained moderate to minimal cash equivalent
reserves in the Portfolio in order to keep a competitive current yield. Credit
quality remained a priority, as it enabled the Portfolio to avoid any credit-
related underperformance during a period when a slowing economy led to some
credit quality deterioration and defaults. Supply and demand technicals have
been supportive of bond prices, during which time a relatively large calendar of
new issues was absorbed by strong retail and institutional interest.

The municipal market environment for the 12-month period ended June 30, 2001
required us to manage the Portfolio in two distinct rate trends, each lasting
approximately six months. At mid-June 2000, 10-year Treasury securities yielded
6%. Our strategy at that time was to be more aggressive with the Portfolio, as
we owned longer duration, discounted securities that offered potential for
capital appreciation as interest rates later declined. While the Portfolio was
fully invested at this stage, performance resulted more from a generous accrual
and current yield than an overly aggressive market position. We stressed higher
credit quality in the middle of last year, and therefore avoided any negative
situations involving declining credit concerns. As 2000 ended, interest rates
declined (nearly 5% for 10-year US Treasury bonds) and the Portfolio assumed a
more defensive structure. Longer-maturity holdings were sold with proceeds
reinvested in serial maturities or prerefunded bonds, which can offer more price
protection should interest rates start to rise again.

Since the beginning of 2001, interest rates trended upward and our defensive
strategy helped cushion the decline in net asset valuation. Cash equivalent
reserves were kept low in order to maintain competitive returns, and our
exposure to inverse floater product was increased to take advantage of an
extremely favorable technical position in the short end of the tax-exempt
market, resulting from aggressive Federal Reserve Board easings. At June 2001,
interest rates were in the center of the recent fiscal year trading range.

We expect our strategy going forward to be to remain focused on achieving
performance results through a more defensive structure, with more attention to
the current yield portion of the total return equation. We also expect to
continue to maintain a higher degree of credit quality since we believe that
focusing on assets in the top rating categories should shield the Portfolio from
most credit deterioration associated with the current economic slowdown.

Limited Maturity Portfolio
For the year ended June 30, 2001, the Limited Maturity Portfolio's Class A,
Class B, Class C and Class D Shares had total returns of +6.07%, +5.69%, +5.59%
and +5.96%, respectively. (Fund results shown do not reflect sales charges and
would be lower if sales charges were included.) Limited Maturity Portfolio kept
a fully invested stance for most of the fiscal year ended June 30, 2001, as we
expected that a weakening economy and falling equity markets would cause the
Federal Reserve Board to ease monetary policy. Low cash reserves and an average
portfolio maturity close to the maximum allowed by the prospectus benefited
performance, since the Fund's short-term nature is directly affected by Federal
Reserve Board policy. However, because of the continued shareholder redemptions,
we maintained a higher credit quality on average than our peer group in an
effort to maintain liquidity.

With continued evidence of a weak economic environment and additional easing by
the Federal Reserve Board, we maintained our relatively aggressive investment
position for the Limited Maturity Portfolio during the second half of the fiscal
year. The Portfolio's average maturity was kept between 1.6 years - 1.8 years
with minimal cash reserves. The average credit quality continued to be AA1 in
order to seek to provide insulation against any net asset value volatility and
for liquidity in meeting shareholder redemptions. This aggressive investment
position enhanced the Fund's performance, since the short-term portion of the
yield curve benefited most from the Federal Reserve Board's reduction of
interest rates.

In Conclusion
We appreciate your ongoing interest in Merrill Lynch Municipal Bond Fund, Inc.,
and we look forward to serving your investment needs in the months and years to

shareholder would pay on fund distributions or the redemption of fund shares.
Figures shown in the "Recent Performance Results" and "Average Annual Total
Return" tables assume reinvestment of all dividends and capital gains
distributions at net asset value on the payable date. Investment return and
principal value of shares will fluctuate so that shares, when redeemed, may be
worth more or less than their original cost. Dividends paid to each class of
shares will vary because of the different levels of account maintenance,
distribution and transfer agency fees applicable to each class, which are
deducted from the income available to be paid to shareholders.

Merrill Lynch Municipal Bond Fund, Inc., June 30, 2001

NOTES TO FINANCIAL STATEMENTS



1. Significant Accounting Policies:
Merrill Lynch Municipal Bond Fund, Inc. (the "Fund") is registered under the
Investment Company Act of 1940 as a diversified, open-end management investment
company. The Fund's financial statements are prepared in conformity with
accounting principles generally accepted in the United States of America, which
may require the use of management accruals and estimates. The Fund's Portfolios
offer four classes of shares under the Merrill Lynch Select Pricing(SM) System.
Shares of Class A and Class D are sold with a front-end sales charge. Shares of
Class B and Class C may be subject to a contingent deferred sales charge. All
classes of shares have identical voting, dividend, liquidation and other rights
and the same terms and conditions, except that Class B, Class C and Class D
Shares bear certain expenses related to the account maintenance of such shares,
and Class B and Class C Shares also bear certain expenses related to the
distribution of such shares. Each class has exclusive voting rights with respect
to matters relating to its account maintenance and distribution expenditures.
The following is a summary of significant accounting policies followed by the
Fund.

(a) Valuation of investments--Insured Portfolio: Where bonds in the Portfolio
have not been insured pursuant to policies obtained by the issuer, the Fund has
obtained insurance with respect to the payment of interest and principal of each
bond. Such insurance is valid as long as the bonds are held by the Fund.

All Portfolios: Municipal bonds and money market securities are traded primarily
in the over-the-counter markets and are valued at the most recent bid price or
yield equivalent as obtained from dealers that make markets in such securities.
Positions in futures contracts and options thereon, which are traded on
exchanges, are valued at closing prices as of the close of such exchanges.
Assets for which market quotations are not readily available are valued at fair
value on a consistent basis using methods determined in good faith by the Fund's
Board of Directors, including valuations furnished by a pricing service retained
by the Fund, which may utilize a matrix system for valuations. The procedures of
the pricing service and its valuations are reviewed by the officers of the Fund
under the general supervision of the Board of Directors.

(b) Derivative financial instruments--The Fund may engage in various portfolio
investment strategies to increase or decrease the level of risk to which the
Fund is exposed more quickly and efficiently than transactions in other types of
instruments. Losses may arise due to changes in the value of the contract or if
the counterparty does not perform under the contract.

* Financial futures contracts--The Fund's Portfolios may purchase or sell
financial futures contracts and options on such futures contracts for the
purpose of hedging the market risk on existing securities or the intended
purchase of securities. 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 Portfolios deposit and maintain as collateral such
initial margin as required by the exchange on which the transaction is effected.
Pursuant to the contract, the Portfolios agree 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 Portfolios as unrealized gains or losses. When the contract is
closed, the Portfolios record 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.

(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. Interest income is recognized on the accrual basis.
Discounts and market premiums are amortized into interest income. The Fund will
adopt the provisions to amortize all premiums and discounts on debt securities
effective July 1, 2001, as now required under the new AICPA Audit and Accounting
Guide for Investment Companies. The cumulative effect of this accounting change
will have no impact on the total net assets of the Fund, but will result in a
$1,299,562 and a $35,232 decrease and a $27,922 increase to the cost of
securities in the Insured, Limited Maturity and National Portfolios,
respectively, and a corresponding $1,299,562 and a $35,232 increase and a
$27,922 decrease to net unrealized appreciation in the Insured, Limited Maturity
and National Portfolios, respectively.

(e) Prepaid registration fees--Prepaid registration fees are charged to expenses
as the related shares are issued.

(f) Dividends and distributions--Dividends from net investment income are
declared daily and paid monthly. Distributions of capital gains are recorded on
the ex-dividend dates. Distributions in excess of realized capital gains are due
primarily to differing tax treatments for futures transactions and post-October
losses.

(g) Expenses--Certain expenses have been allocated to the individual Portfolios
in the Fund on a pro rata basis based upon the respective aggregate net asset
value of each Portfolio included in the Fund.

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. The Fund has also entered into a
Distribution Agreement and Distribution Plans with FAM Distributors, Inc.
("FAMD" or the "Distributor"), which is a wholly-owned subsidiary of Merrill
Lynch Group, Inc.

FAM is responsible for the management of the Fund's portfolios and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operation of the Fund. For such services, FAM receives at the end of each
month a fee with respect to each Portfolio at the annual rates set forth below
which are based upon the average daily value of the Fund's net assets.

In excess of $1.5 billion                .35         .475         .325

Pursuant to the Distribution Plans adopted by the Fund in accordance with Rule
12b-1 under the Investment Company Act of 1940, the Fund pays the Distributor
ongoing account maintenance and distribution fees. The fees are accrued daily
and paid monthly at annual rates based upon the average daily net assets of the
shares as follows:

              Account Maintenance Fees                Distribution Fees
                                    Limited                           Limited

Class D     .25         .25          .10           --        --           --

Pursuant to a sub-agreement with the Distributor, Merrill Lynch, Pierce, Fenner
& Smith Incorporated ("MLPF&S"), a subsidiary of ML & Co., also provides account
maintenance and distribution services to the Fund. The ongoing account

5. Short-Term Borrowings:
On December 1, 2000, the Fund, along with certain other funds managed by MLIM
and its affiliates, renewed and amended a $1,000,000,000 credit agreement with
Bank One, N.A. and certain other lenders. The Fund may borrow under the credit
agreement to fund shareholder redemptions and for other lawful purposes other
than for leverage. The Fund may borrow up to the maximum amount allowable under
the Fund's current prospectus and statement of additional information, subject
to various other legal, regulatory or contractual limits. The Fund pays a
commitment fee of .09% per annum based on the Fund's pro rata share of the
unused portion of the facility. Amounts borrowed under the facility bear
interest at a rate equal to, at each fund's election, the Federal Funds rate
plus .50% or a base rate as determined by Bank One, N.A. The Fund did not borrow
under the facility during the year ended June 30, 2001.

6. Capital Loss Carryforward:
At June 30, 2001, the Insured Portfolio had a net capital loss carryforward of
approximately $50,189,000, of which $17,630,000 expires in 2008 and $32,559,000
expires in 2009; the National Portfolio had a net capital loss carryforward of
approximately $44,931,000, of which $25,616,000 expires in 2008 and $19,315,000
expires in 2009; and the Limited Maturity Portfolio had a net capital loss
carry-forward of approximately $2,474,000, of which $1,928,000 expires in 2003,
$120,000 expires in 2008 and $426,000 expires in 2009. These amounts will be
available to offset like amounts of any future taxable gains.

7. Reorganization Plan:
On March 13, 2001, the Fund's Board of Directors approved a plan of
reorganization, subject to shareholder approval and certain other conditions,
whereby the National Portfolio would acquire substantially all of the assets and
liabilities of Merrill Lynch Arkansas Municipal Bond Fund, Merrill Lynch
Colorado Municipal Bond Fund and Merrill Lynch New Mexico Municipal Bond Fund in
exchange for newly issued shares of the Fund. These Funds are registered, non-
diversified, open-end management investment companies. All four entities have a
similar investment objective and are managed by FAM.

INDEPENDENT AUDITORS' REPORT

The Board of Directors and Shareholders, Merrill Lynch Municipal Bond Fund,
Inc.:
We have audited the accompanying statements of assets and liabilities, including
the schedules of investments, of Merrill Lynch Municipal Bond Fund, Inc.
(comprising, respectively, the Insured, National and Limited Maturity
Portfolios) as of June 30, 2001, the related statements of operations for the
year then ended and changes in net assets for each of the years in the two-year
period then ended, and the financial highlights for each of the years in the
five-year period then ended. These financial statements and the financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and the financial
highlights based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements and the financial highlights are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned at June 30, 2001 by correspondence with the custodian and
brokers. Where replies were not received from brokers, we performed other
auditing procedures. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of each of the
respective portfolios constituting the Merrill Lynch Municipal Bond Fund, Inc.
as of June 30, 2001, the results of their operations, the changes in their net
assets, and their financial highlights for the respective stated periods in
