Merrill Lynch Municipal Bond Fund, Inc. Box 9011 Princeton, NJ 08543-9011 A Letter From the President Dear Shareholder As we ended the current period, all eyes were on the Federal Reserve Board (the Fed). In a much-anticipated move, the Fed raised the Federal Funds rate on June 30 for the first time in four years, bringing the target rate to 1.25%, up from a 45-year low of 1%. The 25 basis point (.25%) increase was the first, but is not expected to be the last, this year as the Fed moves to "normalize" interest rates in the face of increasing inflation. The Fed has reiterated its intention to take a "measured" approach to interest rate increases in an effort to avoid upsetting the economy or the financial markets. Still, in its very deliberate wording, the Fed has stated that it may move more aggressively if inflation and economic growth indicate the need. In any case, interest rates are likely to remain low by historical standards for some time, particularly if the Fed does maintain its commitment to a gradual tightening. To provide some perspective, the Federal Funds rate was at 6.5% before the current easing cycle began in 2001 and had reached double-digits in the late 1970s and early 1980s. The transition to higher interest rates can cause concern among equity and fixed income investors alike. For bond investors, rising interest rates means the value of older bonds declines because they carry the former lower interest rates. However, because municipal bonds offer the advantage of tax-exempt income, they continue to be an attractive alternative for many fixed income investors. For the 12-month period ended June 30, 2004, municipal bonds outperformed their taxable counterparts with a return of +.76% for the Lehman Brothers Municipal Bond Index compared to +.32% for the Lehman Brothers Aggregate Bond Index. June month-end also brought the transfer of power in Iraq. Like the Fed tightening, this was a pivotal event. However, the outcome and the market repercussions are less easy to predict. We do know that markets will always fluctuate and that there are many uncertainties - including the possibility of geopolitical events - that can translate into negative market movements. Still, the U.S. economy is much stronger today than it was just one year ago. With this in mind, we encourage you to revisit your portfolio and your asset allocation strategy to ensure you are well positioned to take advantage of the opportunities that lie ahead. Importantly, you should consult with your financial advisor, who can help you assess the market and economic environment and then develop a strategy most suitable for your circumstances and financial goals. 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, (Terry K. Glenn) Terry K.

MERRILL LYNCH MUNICIPAL BOND FUND, INC., JUNE 30, 2004 A Discussion With Your Portfolio Managers As interest rates began to rise from their historically low levels, the Portfolios' defensive positioning helped to limit sensitivity to yield volatility while also protecting net asset value. Describe the recent market environment relative to municipal bonds. Amid considerable volatility, long-term and short-term bond yields ended the 12-month period considerably higher than where they began. The increase in yields and corresponding fall in prices resulted from concerns that a resurgent economy would lead to inflation, which in turn would encourage the Federal Reserve Board (the Fed) to raise short-term interest rates. In fact, the Fed did increase interest rates 25 basis points (.25%) on June 30, 2004, but suggested that its approach to future interest rate hikes would be gradual. As the period began, bond yields were on the rise as an increasing amount of data indicated a fast-improving economy. By mid-August, yields on U.S. Treasury bonds had risen to 5.45%. Over the next several months, however, yields changed course and began to fall as bond prices rose. Despite the strong economic growth, investors were convinced that lackluster employment data and faltering consumer confidence would cause the Fed to maintain rates at current low levels for some time. By mid-March 2004, yields on long-term U.S. Treasury bonds fell 80 basis points from their August high to 4.65%. In early April, unexpected gains in job growth, improvements in consumer confidence and rising consumer spending prompted yields to rise again (as prices again declined). Investors reversed their prior expectations and concluded that the Fed would indeed be forced to raise interest rates to ward off potential inflation. By mid-May, long-term U.S. Treasury bond yields had risen above 5.45%. Later, as fears of inflation diminished somewhat, yields on the U.S. Treasury benchmark bond fell once more, but - at 5.29% - still ended the period 70 basis points above year-ago levels. The yield on the 10-year U.S. Treasury note stood at 4.58% on June 30, 2004, an increase of more than 100 basis points over the 12-month period. In the municipal bond market, tax-exempt issues also saw considerable variability in yields, though the volatility was more subdued than in the U.S. Treasury market. Yields on long-term revenue bonds, as measured by the Bond Buyer Revenue Bond Index, rose approximately 40 basis points during the year. Thirty-year Aaa-rated bonds saw their yields rise more than 55 basis points to 5.02%, as reported by Municipal Market Data, while yields on Aaa-rated bonds with 10-year maturities rose more than 70 basis points. The more marked increase in 10-year bond yields may be attributed to the fact that several large issues have been heavily concentrated in the 10-year - 20-year range. The resulting supply imbalance prompted higher intermediate bond yields (and lower prices). Yields on Aaa-rated two-year bonds increased even further, rising more than 80 basis points over the past year. Longer-maturity and lower-rated issues continued to benefit from more favorable supply/demand factors and, therefore, experienced less price depreciation. Overall, more than $370 billion in new long-term tax-exempt bonds were issued nationwide during the period, a 5% decline compared to the prior 12 months. New-issue municipal volume is expected to be manageable for the remainder of 2004 and should continue to support the tax-exempt market's favorable technical position. This, in turn, should allow the municipal market to outperform its taxable counterparts in the coming months. LIMITED MATURITY PORTFOLIO How did the Portfolio perform during the period in light of the existing market conditions? For the 12-month period ended June 30, 2004, Limited Maturity Portfolio's Class A, Class B, Class C and Class I Shares had total returns of +.50%, +.24%, +.23% and +.59%, respectively. For the same period, the Portfolio's unmanaged benchmarks, the Lehman Brothers Municipal Bond 3-Year General Obligation Bond Index and the Lehman Brothers Municipal Bond Index, had respective returns of +.62% and +.76%. (Portfolio results shown do not reflect sales charges and would be lower if sales charges were included. Complete performance information can be found on pages 9 - 16 of this report to shareholders.) MERRILL LYNCH MUNICIPAL BOND FUND, INC., JUNE 30, 2004 A Discussion With Your Portfolio Managers (continued) In general, the Portfolio has more limited investment parameters than its benchmarks. While the indexes, particularly the Lehman Brothers Municipal Bond Index, measure the performance of longer- dated, higher-yielding securities, the Portfolio is limited to a maximum average maturity of two years. Given the low-interest-rate environment during most of the past year, the longer end of the yield curve offered more attractive yields, putting the Portfolio at a relative disadvantage. The Portfolio's performance relative to the Lipper Short Municipal Debt Funds category was more favorable. For the 12-month period ended June 30, 2004, the Lipper category had an average return of +.41%. Much like our portfolio, Funds in the Short Municipal Debt Funds category invest primarily in municipal debt issues with dollar- weighted average maturities of less than three years. The Fund's competitive returns during the period can be attributed to our defensive positioning - maintaining a relatively short duration and higher cash reserves. This stance tended to weaken relative performance during the first half of the period, when interest rates were generally falling. However, it had a positive effect on results as the period progressed and rates began rising, as our Portfolio was better prepared to weather the volatility than less-defensive portfolios. What changes were made to the Portfolio during the period? Throughout the period, we kept the Portfolio's duration - its sensitivity to interest rate fluctuations - below that of our benchmark. With interest rates at historically low levels, we were anticipating an eventual increase from the Federal Reserve Board (the Fed) and believed the risk of extending the Portfolio's maturity outweighed the potential short-term performance benefits of such a move. As the period progressed, it appeared more likely that the Fed would raise short-term rates to combat inflationary pressures. Because the bond market had been anticipating this move for some time, municipal bond yields were rising throughout much of the reporting period, well before the Fed's official rate increase on June 30, 2004. In this environment, when making new purchases for the Portfolio, we generally focused on higher-quality bonds, as well as on those offering relatively high coupon payments--both of which tend to hold their value better in rising-rate environments. In mid-May and early June 2004, after bond yields had risen substantially, we saw a temporary buying opportunity in bonds with two-year durations. We took advantage of the opportunity to capture some incremental yield. Finally, throughout the past 12 months, we continued to monitor the limited-maturity municipal marketplace for occasional relative value opportunities. When such opportunities presented themselves, we looked to purchase these securities in an effort to enhance short- term performance. How would you characterize the Portfolio's position at the close of the period? As the period ended, the Portfolio was positioned for additional interest rate increases from the Fed and generally rising tax-exempt bond yields. Further Fed interest rate hikes would have a direct impact on the Portfolio, as we focus our investments on municipal securities with near-term maturities. In this environment, we continue to focus on high-coupon and high-quality bonds to moderate the effects of rising interest rates on the Portfolio. In addition, because of the Portfolio's short-term nature, we have the opportunity to reinvest maturing bonds at higher interest rates as the Fed continues its tightening program - adding to yield and performance. We will continue to monitor economic data and their probable effects on the Fed's monetary policy. As market conditions evolve, we will serve our shareholders by tailoring the Portfolio's positioning to reflect those changing conditions. Peter J. Hayes Vice President and Senior Portfolio Manager June 9, 2004 INSURED PORTFOLIO How did the Portfolio perform during the period in light of the existing market conditions? For the 12-month period ended June 30, 2004, Insured Portfolio's Class A, Class B, Class C and Class I Shares had total returns of +.10%, -.53%, -.58% and +.35%, respectively. For the same period, the Portfolio's benchmark, the Lehman Brothers Municipal Bond Index, returned +.76% (Portfolio results shown do not reflect sales charges and would be lower if sales charges were included. Complete performance information can be found on pages 9 - 16 of this report to shareholders.) MERRILL LYNCH MUNICIPAL BOND FUND, INC., JUNE 30, 2004 The variance in returns compared to the benchmark is not surprising, as the Portfolio is limited primarily to investments in insured securities while the Index measures the broader municipal bond market. During the past 12 months, the performance of insured municipal bonds trailed uninsured securities, particularly non- investment-grade credits, by a wide margin amid a market environment in which investors were increasingly comfortable with assuming risk. The Portfolio's performance was more in line with its comparable Lipper category of Insured Municipal Debt Funds, which had an average return of -.51% for the 12-month period. (Funds in this Lipper category invest primarily in municipal debt issues in the top four credit-rating categories.) Relative to the Lipper group, the Portfolio's performance benefited from our emphasis on securities offering an above-average current yield as well as from our relatively defensive posture, which served to protect net asset value against the risk of rising interest rates. In addition, an emphasis on 20-year securities helped performance, as that represented one of the strongest-performing segments of the yield curve during the past 12 months. What changes were made to the Portfolio during the period? Throughout the period, we continued to focus on securities that we felt represented the best relative value in the insured municipal marketplace. In our view, tax-exempt California bonds provided one such investment opportunity, as budget problems depressed the state's municipal bond prices. Although California's financial situation improved toward the end of the period, we still believe that insured California bonds are attractively priced on a relative basis and that they may continue to perform well in the near future. In addition, we began to shift our focus further out on the municipal yield curve during the period. As the curve steepened significantly between 15 years - 30 years - indicating greater amounts of income available to investors in longer bonds - we sought to take advantage of the situation by investing in bonds with slightly longer maturities. In particular, we emphasized bonds with maturities between 23 years - 26 years, an area of the yield curve we thought offered particular value. At the same time, we de-emphasized shorter bonds, which we believed would encounter more challenging performance ahead. How would you characterize the Portfolio's position at the close of the period? At period-end, the Portfolio was fully invested and, in anticipation of higher interest rates, defensively positioned. We continue to emphasize competitive yield and preservation of the Portfolio's net asset value. While we have begun efforts to restructure the Portfolio with bonds offering slightly longer maturity dates, those securities added in recent months have tended to be premium-coupon bonds with defensive characteristics. Such a defensive posture has enabled the Fund to increase its yield-generation potential while helping insulate it from the volatility expected to accompany a rising-interest-rate environment. Robert A. DiMella Vice President and Senior Portfolio Manager June 14, 2004 NATIONAL PORTFOLIO How did the Portfolio perform during the period in light of the existing market conditions? For the 12-month period ended June 30, 2004, National Portfolio's Class A, Class B, Class C and Class I Shares had total returns of +2.62%, +2.10%, +2.05% and +2.88%, respectively. For the same period, the Portfolio's benchmark, the Lehman Brothers Municipal Bond Index, returned +.76%. (Portfolio results shown do not reflect sales charges and would be lower if sales charges were included. Complete performance information can be found on pages 9 - 16 of this report to shareholders.) The Portfolio's comparable Lipper category of General Municipal Debt Funds had an average return of +.32% for the same 12-month period. (Funds in this Lipper category invest primarily in municipal debt issues in the top four credit- rating categories.) MERRILL LYNCH MUNICIPAL BOND FUND, INC., JUNE 30, 2004 A Discussion With Your Portfolio Managers (concluded) The Portfolio's performance during the period benefited from its emphasis on securities offering higher-than-average current yields. At the end of the period, the Portfolio maintained an average coupon of 6.35%, well above the level of current general market bonds trading at par value. In addition, Portfolio performance benefited from our relatively defensive positioning. By keeping the Portfolio's duration - its sensitivity to changes in interest rates - lower than that of similar funds, the Portfolio was less negatively influenced by rising rates, which lower the prices of outstanding bonds. What changes were made to the Portfolio during the period? We adjusted the Portfolio's credit quality, especially in the final three months of the period, by increasing our emphasis on lower- rated credits. Working closely with our Municipal Research Group, we identified selected value opportunities in certain lower-rated sectors of the market, while still remaining within the credit standards outlined in the Portfolio's prospectus. In addition to providing the Portfolio with additional yield, these lower-rated securities tend to have lower durations and, therefore, are not as vulnerable to further increases in interest rates. Despite these moves, the Portfolio still maintained a high degree of credit quality as of the end of June 2004, with approximately 45% of net assets invested in AAA-rated securities. The Fund's stake in below- investment-grade credits stood at about 19% of total assets. Toward the end of the period, bond yields rose significantly in advance of an expected hike in short-term interest rates by the Federal Reserve Board. As tax-exempt yields surpassed 5%, we began to purchase some longer-maturity discount bonds to temporarily take advantage of attractive yields (and correspondingly low prices). These purchases represented only a small percentage of the Portfolio's overall assets. We also kept a careful eye on movements in the municipal marketplace, intending to sell some of these positions if bond prices were to rise. How would you characterize the Portfolio's position at the close of the period? Despite our recent purchase of more aggressively structured securities, the Portfolio remains defensively positioned. We are looking for a more sustained rise in interest rates before committing to a more aggressive portfolio structure. At period-end, the Portfolio was nearly fully invested, maintaining only a small cash reserve of less than 1% of total assets to meet cash-flow needs. Finally, we will continue to monitor credit spreads, which have been tightening during the past year as investors have assumed a greater degree of risk. If that tightening continues, we may look to reduce exposure to some of the Portfolio's higher-yielding, lower- rated securities. Walter C.

None of the past results shown should be considered a representation of future performance. Current performance may be lower or higher than the performance data quoted. Refer to www.mlim.ml.com to obtain more current performance information. Performance results do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Figures shown in each of the following tables assume reinvestment of all dividends and capital gain distributions, if any, 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. The Fund's Investment Adviser waived a portion of its management fee. Without such waiver, performance would have been lower.

See Notes to Financial Statements. MERRILL LYNCH MUNICIPAL BOND FUND, INC., JUNE 30, 2004 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 amended, as a diversified, open-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. The Fund's Portfolios offer four classes of shares. Shares of Class A and Class I 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 A, Class B and Class C 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. Income, expenses (other than expenses attributable to a specific class) and realized and unrealized gains and losses on investments and foreign currency transactions are allocated daily to each class based on its relative net assets. 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 Portfolio. 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 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. * Financial futures contracts--The Fund's Portfolios 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 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. * 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 pay or receive interest on a specified notional contract amount, commencing on a specified future effective date, unless terminated earlier. The value of the agreement is determined by quoted fair values received daily by the Fund from the counterparty. 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 Portfolio's amortize all premiums and discounts on debt securities. MERRILL LYNCH MUNICIPAL BOND FUND, INC., JUNE 30, 2004 Notes to Financial Statements (continued) (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. (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. (h) Reclassification--U.S generally accepted accounting principles require that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. Accordingly, during the current year, with respect to the Insured Portfolio, $594 has been reclassified between accumulated net realized capital losses and undistributed net investment income as a result of permanent differences attributable to amortization methods for premiums and discounts on fixed income securities and taxable ordinary income dividends received for tax purposes. In addition, with respect to the National Portfolio, $3,468 has been reclassified between accumulated net realized capital gains and undistributed net investment income and $188,884 has been reclassified between undistributed net investment income and paid-in capital in excess of par as a result of permanent differences attributable to amortization methods for premiums and discounts on fixed income securities and non-deductible reorganization expenses. These reclassifications have no effect on net assets or net asset values per share. 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") comprising the Insured, National and Limited Maturity Portfolios as of June 30, 2004, and the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and 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 as of June 30, 2004, 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, the financial statements and financial highlights referred to above 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, 2004, the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and their financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

Audit, audit-related and tax compliance services provided to the registrant on an annual basis require specific pre-approval by the Committee. The Committee also must approve other non-audit services provided to the registrant and those non-audit services provided to the registrant's affiliated service providers that relate directly to the operations and the financial reporting of the registrant. Certain of these non-audit services that the Committee believes are a) consistent with the SEC's auditor independence rules and b) routine and recurring services that will not impair the independence of the independent accountants may be approved by the Committee without consideration on a specific case-by-case basis ("general pre-approval"). However, such services will only be deemed pre-approved provided that any individual project does not exceed $5,000 attributable to the registrant or $50,000 for all of the registrants the Committee oversees. Any proposed services exceeding the pre-approved cost levels will require specific pre- approval by the Committee, as will any other services not subject to general pre-approval (e.g., unanticipated but permissible services). The Committee is informed of each service approved subject to general pre-approval at the next regularly scheduled in-person board meeting.
