A LETTER FROM THE CEO

Dear Shareholder:

We are pleased to present this annual report for Dreyfus Municipal Money Market Fund, Inc., covering the 12-month period from June

1, 2006, through May 31, 2007.

The U.S. economy continued to moderate during the reporting period as cooling housing markets took their toll on consumer and business spending. Labor markets, however, remained quite strong, and key measures of inflation have stayed stubbornly above the Federal Reserve’s stated “comfort zone.” Our economists believe that the anemic rate of U.S. economic growth recorded in the first quarter of 2007 should be the weakest reading of the current midcycle slowdown, and economic growth is likely to recover eventually to a near-trend pace.

The likely implications of our economic outlook include a long pause in Fed policy, a modest drop in 10-year Treasury bond yields (and consequent rise in price) and, in the absence of an as-yet unforeseen event, persistently tight yield spreads along the money market spectrum.We expect these developments to produce both challenges and opportunities for fixed-income investors. As always, your financial advisor can help you position your investments for these trends.

Thank you for your continued confidence and support.

DISCUSSION OF FUND PERFORMANCE

For the period from June 1, 2006, through May 31, 2007, as provided by Colleen Meehan, Senior Portfolio Manager

Market and Fund Performance Overview

Yields of tax-exempt money market instruments remained relatively stable over the reporting period as the Federal Reserve Board (the “Fed”) refrained from adjusting short-term interest rates from July 2006 through the reporting period’s end.

For the 12-month period ended May 31, 2007, the fund produced a yield of 3.08% . Taking into account the effects of compounding, the fund produced an effective yield of 3.13% .1

The Fund’s Investment Approach

The fund seeks as high a level of current income exempt from federal income tax as is consistent with the preservation of capital and the maintenance of liquidity.

In pursuing this objective, we employ two primary strategies. First, we normally attempt to add value by investing substantially all of the fund’s net assets in high-quality short-term municipal obligations throughout the United States and its territories that provide income exempt from federal personal income tax. Second, we actively manage the fund’s average maturity based on our anticipation of supply-and-demand changes in the short-term municipal marketplace and interest-rate cycles while anticipating liquidity needs.

For example, if we expect an increase in short-term supply, we may decrease the average maturity of the fund, which could enable us to take advantage of opportunities when short-term supply increases. Generally, yields tend to rise when there is an increase in new-issue supply competing for investor interest. New securities are generally issued with maturities in the one-year range, which in turn may lengthen the fund’s average maturity if purchased. If we anticipate limited new-issue supply, we may then look to extend the fund’s average

maturity to maintain then-current yields for as long as we believe practical. At other times, we try to maintain an average maturity that reflects our view of short-term interest-rate trends and future supply-and-demand considerations.

Interest Rates Stabilize in a Slowing U.S. Economy

In the months leading up to the start of the reporting period, the U.S. economy was growing robustly and inflationary pressures were intensifying as energy prices surged toward new record highs. As a result, in late June 2006, the Fed implemented its sixteenth consecutive increase of short-term interest rates since June 2004, driving the overnight federal funds rate to 5.25% .

However, economic conditions changed significantly over the summer, when the U.S. housing market softened and energy prices fell, helping to relieve investors’ inflation concerns.The Fed lent credence to a more moderate inflation outlook when it refrained from raising interest rates over the remainder of the reporting period, citing the likelihood that slower economic growth would reduce inflationary pressures.

Although Fed policy remained unchanged, investors’ expectations of future interest-rate moves fluctuated with each new release of economic data. On one hand, moderating economic growth indicated to some investors that the Fed might begin to reduce interest rates to avoid a potential recession. On the other hand, stubborn inflationary pressures, including a strong U.S. labor market, suggested that the Fed would remain on hold, effectively delaying a change in monetary policy.

Yield Differences Decline Along the Market’s Maturity Range

In this environment, yields of tax-exempt money market securities stabilized along with interest rates.However,yields of longer-dated instruments declined, leaving little difference in the yields of securities with maturities between six months and four years. Investors therefore continued to focus on tax-exempt instruments maturing in six months or less.

Technical factors put downward pressure on tax-exempt money market yields. The growing U.S. economy reduced the borrowing

needs of several states and municipalities, and some issuers revised their borrowing programs to rely more heavily on short-term variable-rate demand notes. Even as the supply of one-year municipal notes declined, investor demand remained strong as evidenced by an increase in money market fund assets to record levels. Since yield differences had declined to historically narrow levels, the tax-exempt money market saw demand from investors who, under more typical market conditions, invest primarily in longer-term fixed-income securities.

We generally maintained the fund’s weighted average maturity in a range we considered to be roughly in line with industry averages. Whenever possible, we attempted to smooth out the fund’s yield by limiting its exposure to variable-rate instruments. Instead, we found opportunities in tax-exempt commercial paper and seasoned municipal notes and bonds with maturities in the three- to six-month range.

Fund Remains Positioned for an Unchanged Fed Policy

Economic data have remained mixed, suggesting to us that the Fed is likely to stay on the sidelines. Indeed, the Fed held interest rates steady at its meeting in May 2007, when it commented that inflation remained a more pressing risk to the economy than recession.

As of the end of the reporting period, the fund’s weighted average maturity was slightly longer than industry averages, due primarily to our focus on commercial paper. In addition, the fund’s weighted average maturity reflected our attempts to capture higher yields that have become available due to seasonal supply-and-demand factors.

UNDERSTANDING YOUR FUND’S EXPENSES (Unaudited)

As a mutual fund investor, you pay ongoing expenses, such as management fees and other expenses. Using the information below, you can estimate how these expenses affect your investment and compare them with the expenses of other funds.You also may pay one-time transaction expenses, including sales charges (loads) and redemption fees, which are not shown in this section and would have resulted in higher total expenses. For more information, see your fund’s prospectus or talk to your financial adviser.

Review your fund’s expenses

The table below shows the expenses you would have paid on a $1,000 investment in Dreyfus Municipal Money Market Fund, Inc. from December 1, 2006 to May 31, 2007. It also shows how much a $1,000 investment would be worth at the close of the period, assuming actual returns and expenses.

Expenses and Value of a $1,000 Investment 
assuming actual returns for the six months ended May 31, 2007 

 
Expenses paid per $1,000     $ 2.91 
Ending value (after expenses)    $1,015.80 

COMPARING YOUR FUND’S EXPENSES WITH THOSE OF OTHER FUNDS (Unaudited)

Using the SEC’s method to compare expenses

The Securities and Exchange Commission (SEC) has established guidelines to help investors assess fund expenses. Per these guidelines, the table below shows your fund’s expenses based on a $1,000 investment, assuming a hypothetical 5% annualized return. You can use this information to compare the ongoing expenses (but not transaction expenses or total cost) of investing in the fund with those of other funds.All mutual fund shareholder reports will provide this information to help you make this comparison. Please note that you cannot use this information to estimate your actual ending account balance and expenses paid during the period.

Expenses and Value of a $1,000 Investment 
assuming a hypothetical 5% annualized return for the six months ended May 31, 2007 

 
Expenses paid per $1,000     $ 2.92 
Ending value (after expenses)    $1,022.04 

Expenses are equal to the fund’s annualized expense ratio of .58%, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period).

NOTES TO FINANCIAL STATEMENTS

NOTE 1—Significant Accounting Policies:

Dreyfus Municipal Money Market Fund, Inc. (the “fund”) is registered under the Investment Company Act of 1940, as amended (the “Act”), as a diversified open-end management investment company. The fund’s investment objective is to maximize current income exempt from federal income tax to the extent consistent with the preservation of capital and the maintenance of liquidity. The Dreyfus Corporation (the “Manager or Dreyfus” ) serves as the fund’s investment adviser. During the reporting period, the Manager was a wholly-owned subsidiary of Mellon Financial Corporation (“Mellon Financial”). Dreyfus Service Corporation (the “Distributor”), a wholly-owned subsidiary of the Manager, is the distributor of the fund’s shares, which are sold to the public without a sales charge. Effective June 30, 2007, the Distributor will be known as MBSC Securities Corporation.

On July 1, 2007, Mellon Financial and The Bank of New York Company, Inc. merged, forming The Bank of New York Mellon Corporation. As part of this transaction, Dreyfus became a wholly-owned subsidiary of The Bank of New York Mellon Corporation.

It is the fund’s policy to maintain a continuous net asset value per share of $1.00; the fund has adopted certain investment, portfolio valuation and dividend and distribution policies to enable it to do so.There is no assurance, however, that the fund will be able to maintain a stable net asset value per share of $1.00.

The fund’s financial statements are prepared in accordance with U.S. generally accepted accounting principles, which may require the use of management estimates and assumptions. Actual results could differ from those estimates.

The fund enters into contracts that contain a variety of indemnifications. The fund’s maximum exposure under these arrangements is unknown.The fund does not anticipate recognizing any loss related to these arrangements.

The Fund 23


NOTES TO FINANCIAL STATEMENTS (continued)

(a) Portfolio valuation: Investments in securities are valued at amortized cost in accordance with Rule 2a-7 of the Act, which has been determined by the Board of Directors to represent the fair value of the fund’s investments.

On September 20, 2006, the Financial Accounting Standards Board (FASB) released Statement of Financial Accounting Standards No. 157 “Fair Value Measurements” (“FAS 157”). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. Management does not believe that the application of this standard will have a material impact on the financial statements of the fund.

(b) Securities transactions and investment income: Securities transactions are recorded on a trade date basis. Interest income, adjusted for accretion of discount and amortization of premium on investments, is earned from settlement date and recognized on the accrual basis. Realized gain and loss from securities transactions are recorded on the identified cost basis. Cost of investments represents amortized cost.

The fund has an arrangement with the custodian bank whereby the fund receives earnings credits, if any, from the custodian when positive cash balances are maintained, which are used to offset custody fees. For financial reporting purposes, the fund includes net earnings credits, if any, as an expense offset in the Statement of Operations.

(c) Dividends to shareholders: It is the policy of the fund to declare dividends daily from investment income-net. Such dividends are paid monthly. Dividends from net realized capital gain, if any, are normally declared and paid annually, but the fund may make distributions on a more frequent basis to comply with the distribution requirements of the Internal Revenue Code of 1986, as amended (the “Code”).To the extent that net realized capital gain can be offset by capital loss carryovers, it is the policy of the fund not to distribute such gain.

24


(d) Federal income taxes: It is the policy of the fund to continue to qualify as a regulated investment company, which can distribute tax exempt dividends, by complying with the applicable provisions of the Code, and to make distributions of income and net realized capital gain sufficient to relieve it from substantially all federal income and excise taxes.

On July 13, 2006, the FASB released FASB Interpretation No. 48 “Accounting for Uncertainty in Income Taxes” (FIN 48). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the fund’s tax returns to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority.Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management does not believe that the application of this standard will have a material impact on the financial statements of the fund.

At May 31, 2007, the components of accumulated earnings on a tax basis were substantially the same as for financial reporting purposes.

The tax character of distributions paid to shareholders during the fiscal periods ended May 31, 2007 and May 31, 2006, were all tax exempt income.

At May 31,2007,the cost of investments for federal income tax purposes was substantially the same as the cost for financial reporting purposes (see the Statement of Investments).

NOTES TO FINANCIAL STATEMENTS (continued)

NOTE 2—Management Fee and Other Transactions with Affiliates:

(a) Pursuant to a management agreement with the Manager, the management fee is computed at the annual rate of .50% of the value of the fund’s average daily net assets and is payable monthly.

(b) Under the Shareholder Services Plan, the fund reimburses the Distributor an amount not to exceed an annual rate of .25% of the value of the fund’s average daily net assets for certain allocated expenses of providing personal services and/or maintaining shareholder accounts. The services provided may include personal services relating to shareholder accounts, such as answering shareholder inquiries regarding the fund and providing reports and other information, and services related to the maintenance of shareholder accounts. During the period ended May 31, 2007, the fund was charged $222,351 pursuant to the Shareholder Services Plan.

The fund compensates Dreyfus Transfer, Inc., a wholly-owned subsidiary of the Manager, under a transfer agency agreement for providing personnel and facilities to perform transfer agency services for the fund. During the period ended May 31, 2007, the fund was charged $108,480 pursuant to the transfer agency agreement.

During the period ended May 31, 2007, the fund charged $4,089 for services performed by the Chief Compliance Officer.

The components of “Due to The Dreyfus Corporation and affiliates” in the Statement of Assets and Liabilities consist of: management fees $337,143, shareholder services plan fees $11,935, chief compliance officer fees $3,748 and transfer agency per account fees $18,200.

(c) Each Board member also serves as a Board member of other funds within the Dreyfus complex. Annual retainer fees and attendance fees are allocated to each fund based on net assets.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Shareholders and Board of Directors Dreyfus Municipal Money Market Fund, Inc.

We have audited the accompanying statement of assets and liabilities, including the statement of investments, of Dreyfus Municipal Money Market Fund, Inc., as of May 31, 2007, and the related statement of operations for the year then ended, the statement of changes in net assets for each of the two years in the period then ended, and financial highlights for each of the years indicated therein.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.We were not engaged to perform an audit of the Fund’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned May 31, 2007 by correspondence with the custodian. 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 Dreyfus Municipal Money Market Fund, Inc. at May 31, 2007, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the indicated years, in conformity with U.S. generally accepted accounting principles.

The aggregate fees billed in the Reporting Periods for non-audit assurance and related services by the Auditor to the Registrant's investment adviser (not including any sub-investment adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by or under common control with the investment adviser that provides ongoing services to the Registrant ("Service Affiliates"), that were reasonably related to the performance of the annual audit of the Service Affiliate, which required pre-approval by the Audit Committee were $0 in 2006 and $0 in 2007.

Note: For the second paragraph in each of (b) through (d) of this Item 4, certain of such services were not pre-approved prior to May 6, 2003, when such services were required to be pre-approved. On and after May 6, 2003, 100% of all services provided by the Auditor were pre-approved as required.

The Registrant's Audit Committee has established policies and procedures (the "Policy") for pre-approval (within specified fee limits) of the Auditor's engagements for non-audit services to the Registrant and Service Affiliates without specific case-by-case consideration. Pre-approval considerations include whether the proposed services are compatible with maintaining the Auditor's independence. Pre-approvals pursuant to the Policy are considered annually.
