DEAR SHAREHOLDER

The Municipal Market Environment
During the three months ended December 31, 1997, long-term fixed-
income bond yields declined to their lowest levels in nearly four 
years. A continued positive domestic inflationary environment provided 
much of the support for the bond market's recent improvement through 
early October 1997. However, during the last two months of 1997, the 
turmoil in the world's financial markets, particularly in the Asian 
equity market, has produced major declines in bond yields. Since 
October 31, 1997, the US Treasury bond market has been the beneficiary 
of a significant flight to quality mainly by foreign investors whose 
own domestic markets have remained very volatile. Prior to the initial 
decline in the Asian equity markets, yields on US Treasury and 
tax-exempt bonds had been little changed. Subsequently, long-term US 
Treasury bond yields have declined almost 50 basis points (0.50%) over 
the last three months to end the year at 5.91%. Tax-exempt revenue 
bond yields, however, have exhibited lesser declines. As measured by 
the Bond Buyer Revenue Bond Index, long-term municipal bond yields 
declined over 20 basis points to 5.40%, their lowest level since 
October 1993.

The increase in new municipal bond issuance over the past six months 
has also prevented the tax-exempt bond market from more closely 
mirroring the yield declines exhibited by its taxable counterpart. 
During the last six months, over $120 billion in new long-term 
municipal bonds were underwritten, an increase of over 30% compared to 
the same period in 1996. As interest rates have continued to decline 
in recent months, new tax-exempt bond issuance has remained strong. 
During the December quarter, almost $65 million in long-term municipal 
securities were issued, an increase of almost 20% versus the quarter 
ended December 31, 1996. During the month of December, over $21 
billion in new long-term municipal securities were underwritten. This 
represented an increase of 9% versus December 1996 levels and the 
greatest December issuance since 1993.

In our opinion, the recent correction in world equity markets has 
enhanced the near-term prospects for continued low, if not declining, 
interest rates in the United States. It is likely that the recent 
correction will result in slower US domestic growth in the coming 
months. This decline is likely to be generated in part by reduced US 
export growth. Additionally, some decline in consumer spending can 
also be expected in response to reduced consumer confidence. Perhaps 
more importantly, it is likely that, barring a dramatic and unexpected 
resurgence in domestic growth, the Federal Reserve Board will be 
unwilling to raise interest rates until the full impact of the equity 
market's corrections can be established.

All these factors suggest that over the near term, interest rates, 
including tax-exempt bond yields, are unlikely to rise by any 
appreciable amount. It is probable, however, that municipal bond 
yields will remain under some relative pressure as a result of 
continued strong new-issue supply. However, the recent pace of 
municipal bond issuance is likely to be unsustainable. Continued 
increases in bond issuance will require lower and lower tax-exempt 
bond yields to generate the economic savings necessary for additional 
municipal bond refinancings. Preliminary estimates of 1998 total 
municipal bond issuance are presently in the $195 billion -- $220 
billion range. These estimates suggest that recent supply pressures 
are likely to abate somewhat next year, or at least, exert only 
minimal technical pressures during 1998. Additionally, municipal bond 
investors are expected to receive approximately $23 billion in January 
coupon payments, bond maturities and proceeds from early redemptions. 
Such assets should serve to intensify investor demand in the near 
future. With tax-exempt bond yields at already attractive yield ratios 
relative to US Treasury bonds (approximately 90% at the end of 
December) any further pressure on the municipal market may well 
represent an attractive investment opportunity.

Portfolio Strategy
Insured Portfolio and National 
Portfolio
A combination of several positive technical and economic factors have 
contributed to a scenario where the fixed-income markets, and the tax-
exempt market in particular, have reached historically low levels of 
nominal interest rates. Over the past six months, we held our 
portfolio strategy for the Insured and National Portfolios of 
maintaining a fully invested posture and using any price declines to 
restructure the Portfolios more aggressively. We sought to maintain a 
high level of current yield and to provide well-above industry average 
tax-exempt income to shareholders. 

At current interest rate levels, we expect to sell some of the 
Portfolios' more aggressively structured, discounted securities, and 
use the proceeds to purchase more income-oriented bonds. Although the 
fundamental economic backdrop for the marketplace is still quite 
supportive, we expect the municipal market to participate only 
marginally in any further price gains. Therefore, we will concentrate 
on enhancing the Portfolios' current returns through diligent research 
to uncover higher-yielding securities within the credit quality limits 
of each Portfolio as detailed in the Fund's prospectus.

Limited Maturity Portfolio
We continued to aggressively position the Limited Maturity Portfolio, 
especially in view of the fact that the Asian financial crisis would 
most likely prevent the Federal Reserve Board from raising interest 
rates. The Portfolio maintained cash in the 1% -- 2% range for most of 
the December quarter. The average life of the Portfolio was maintained 
at approximately 1.8 years, close to its permissible maximum of 2 
years. Purchases were concentrated in the two-year -- four-year range 
to allow for maximum capital appreciation, while the focus was kept on 
higher-coupon bonds in order to seek to provide a high level of 
current income to shareholders. We anticipate maintaining this 
strategy in the coming months as fears of slower economic growth and 
deflation keep Federal Reserve Board policy on hold, with a possible 
bias for monetary policy easing in the future.

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

Sincerely,

Portfolio incurs a maximum initial sales charge (front-end load) of 1% 
and bears no ongoing distribution or account maintenance fees.

[bullet] Class B Shares are subject to a maximum contingent deferred 
sales charge of 4% if redeemed during the first year, decreasing 1% 
each year thereafter to 0% after the fourth year for Insured and 
National Portfolios. Limited Maturity Portfolio is subject to a

None of the past results shown should be considered a representation 
of future performance. Figures shown in the "Average Annual Total 
Return" tables as well as the total returns and cumulative total 
returns in the "Performance Summary" 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.

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. These unaudited financial statements 
reflect all adjustments which are, in the opinion of management, 
necessary to a fair statement of the results for the interim period 
presented. All such adjustments are of a normal recurring nature. The 
Fund's Portfolios offer four classes of shares under the Merrill Lynch 
Select PricingSM 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 strategies to seek to increase its return by hedging its 
portfolio against adverse movements in the debt markets. Losses may 
arise due to changes in the value of the contract or if the 
counterparty does not perform under the contract.

[bullet] Financial futures contracts -- The Fund's Portfolios may 
purchase or sell interest rate 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 deposits and maintains 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). Interest income is recognized on the accrual 
basis. Discounts and market premiums are amortized into interest 
income. Realized gains and losses on security transactions are 
determined on the identified cost basis.

(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. 

2. Investment Advisory Agreement and Transactions with Affiliates:
