A LETTER FROM THE PRESIDENT

Dear Shareholder:

We are pleased to present this semiannual report for Dreyfus New Jersey Municipal Money Market Fund, Inc., covering the six-month period from December 1, 2012, through May 31, 2013. For information about how the fund performed during the reporting period, as well as general market perspectives, we provide a Discussion of Fund Performance on the pages that follow.

The U.S. economic recovery gained traction over the reporting period, but remained slower than historical norms. On one hand, the expansion has been fueled by gradually falling unemployment, recovering housing markets, rapid growth in domestic oil and gas production, and, perhaps most significant, the aggressively stimulative monetary policy of the Federal Reserve Board (the “Fed”). On the other hand, several factors have weighed on the nation’s economic growth rate, including relatively sluggish demand for exports to Europe and the emerging markets, higher tax rates for some Americans, and more restrictive fiscal policies stemming from sequestration. While yields of longer term bonds climbed in response to these developments, yields of money market instruments remained anchored by the Fed’s historically low target for the overnight federal funds rate.

In our analysis, real GDP growth seems poised to accelerate modestly over the remainder of 2013. In fact, we expect the relatively mild economic expansion to remain intact domestically and globally over the next several years. The moderate pace of the recovery implies that the risks of consumer price inflation are limited, making it unlikely that the Fed will adopt expansion-threatening, restrictive policies anytime soon. As always, we encourage you to discuss our observations with your financial advisor.

Thank you for your continued confidence and support.

Sincerely,

J. Charles Cardona
President
The Dreyfus Corporation

DISCUSSION OF FUND PERFORMANCE

For the period of December 1, 2012, through May 31, 2013, as provided by Joseph Irace, Senior Portfolio Manager

Fund and Market Performance Overview

For the six-month period ended May 31, 2013, Dreyfus New Jersey Municipal Money Market Fund’s shares produced annualized yields of 0.00%. Taking into account the effects of compounding, the fund’s shares produced annualized effective yields of 0.00%.¹

Yields of tax-exempt money market instruments stayed near historical lows throughout the reporting period, as short-term interest rates remained anchored by an overnight federal funds rate between 0% and 0.25% despite evidence of more robust economic growth.

The Fund’s Investment Approach

The fund’s objective is to seek as high a level of current income exempt from federal and New Jersey state income taxes as is consistent with the preservation of capital and the maintenance of liquidity.The fund also seeks to maintain a stable $1.00 share price. To pursue its goal, the fund normally invests substantially all of its assets in short-term, high-quality municipal obligations that provide income exempt from federal and New Jersey state personal income taxes.The fund also may invest in high-quality, short-term structured notes, which are derivative instruments whose value is tied to underlying municipal obligations.

When pursuing the fund’s objective, we employ two primary strategies. First, we attempt to add value by constructing a portfolio of high-quality, tax-exempt money market municipal obligations that provide income exempt from federal and New Jersey state income taxes. Second, we actively manage the fund’s average maturity in anticipation of interest-rate trends and supply-and-demand changes in New Jersey’s short-term municipal marketplace.

For example, if we expect an increase in short-term supply, we may reduce the weighted average maturity of the fund, which should better position the fund to purchase new securities with higher yields, if higher yields materialize.Yields tend to

DISCUSSION OF FUND PERFORMANCE (continued)

rise when there is an increase in new-issue supply competing for investor interest. New securities generally are issued with maturities in the one-year range and tend to lengthen the fund’s weighted average maturity if purchased. If we anticipate limited new-issue supply, we may extend the fund’s average maturity to maintain then-current yields for as long as we think 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.

Gradual Economic Recovery Continues

The reporting period saw a generally improving economic environment, as U.S. GDP growth increased from a 0.4% annualized rate during the fourth quarter of 2012 to 2.4% over the first quarter of 2013. In addition, the unemployment rate declined gradually, and housing markets exhibited long-awaited signs of recovery.

Despite these positive developments, the Federal Reserve Board (the “Fed”) indicated that today’s historically low interest rates are unlikely to change until unemployment declines further. In this environment, individual investors have focused on higher yielding securities in the longer term municipal bond market. Demand for securities issued by municipalities also remained strong among nontraditional buyers, such as separately managed accounts and intermediate bond funds, due to attractive tax-exempt yields compared to taxable securities and narrow yield differences across the zero- to three-year maturity spectrum. Nonetheless, yields on high-quality, one-year municipal notes remained near historical lows over the reporting period, and increased investor demand for variable rate demand notes has kept yields of shorter term securities steady.

The economic recovery in New Jersey has lagged most other states, and New Jersey continues to struggle with a heavy debt burden, unfunded pension liabilities, and structural budget deficits.

Credit Selection Remains Paramount

Due to narrow yield differences along the maturity spectrum, as well as ongoing regulatory uncertainty, most tax-exempt money market funds have maintained relatively short weighted average maturities compared to historical averages. However, unlike many other states, New Jersey has offered opportunities for higher yields from longer dated maturities, and we set the fund’s weighted average maturity in a range that was modestly longer than industry averages.

Moreover, well-researched credit selection has remained paramount. As we have for some time, we favored state general obligation bonds; essential service revenue bonds backed by revenues from water, sewer, and electric facilities; certain local credits with strong financial positions and stable tax bases; and health care and education issuers with stable credit characteristics.We generally continued to shy away from instruments issued by localities that depend heavily on state aid.

Low Rates Likely to Persist

We are cautiously optimistic regarding U.S. economic prospects.While the Fed has indicated that it may begin to taper off its ongoing, open-ended quantitative easing program later this year, it also has made clear that short-term interest rates are likely to remain low for some time to come. Consequently, we believe that the prudent course continues to be an emphasis on preservation of capital and liquidity.

June 17, 2013

An investment in the fund is not insured or guaranteed by the FDIC or any other government agency. Although the fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the fund.

Short-term municipal securities holdings involve credit and liquidity risks and risk of principal loss.

1 Annualized effective yield is based upon dividends declared daily and reinvested monthly. Past performance is no

guarantee of future results.Yields fluctuate. Income may be subject to state and local taxes for non-New Jersey

residents, and some income may be subject to the federal alternative minimum tax (AMT) for certain investors.Yields

provided reflect the absorption of certain fund expenses by The Dreyfus Corporation pursuant to an undertaking in

effect that may be extended, terminated or modified at any time. Had these expenses not been absorbed, fund yields

would have been lower.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1—Significant Accounting Policies:

Dreyfus New Jersey Municipal Money Market Fund, Inc. (the “fund”) is registered under the Investment Company Act of 1940, as amended (the “Act”), as a non-diversified open-end management investment company.The fund’s investment objective is to seek as high a level of current income exempt from federal and New Jersey state income taxes as is consistent with the preservation of capital and the maintenance of liquidity. The Dreyfus Corporation (the “Manager” or “Dreyfus”), a wholly-owned subsidiary of The Bank of New York Mellon Corporation (“BNY Mellon”), serves as the fund’s investment adviser. MBSC Securities 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.

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 Financial Accounting Standards Board (“FASB”) Accounting Standards Codification is the exclusive reference of authoritative U.S. generally accepted accounting principles (“GAAP”) recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the Securities and Exchange Commission (“SEC”) under authority of federal laws are also sources of authoritative GAAP for SEC registrants. The fund’s financial statements are prepared in accordance with GAAP, 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 (Unaudited) (continued)

(a) Portfolio valuation: Investments in securities are valued at amortized cost in accordance with Rule 2a-7 under the Act. If amortized cost is determined not to approximate market value, the fair value of the portfolio securities will be determined by procedures established by and under the general supervision of the fund’s Board of Directors (the “Board”).

The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e., the exit price). GAAP establishes a fair value hierarchy that prioritizes the inputs of valuation techniques used to measure fair value.This hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).

Additionally, GAAP provides guidance on determining whether the volume and activity in a market has decreased significantly and whether such a decrease in activity results in transactions that are not orderly. GAAP requires enhanced disclosures around valuation inputs and techniques used during annual and interim periods.

Various inputs are used in determining the value of the fund’s investments relating to fair value measurements.These inputs are summarized in the three broad levels listed below:

Level 1—unadjusted quoted prices in active markets for identical investments.

Level 2—other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.).

Level 3—significant unobservable inputs (including the fund’s own assumptions in determining the fair value of investments).

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. For example, money market securities are valued using amortized cost, in accordance with rules under the Act. Generally, amortized cost

approximates the current fair value of a security, but since the value is not obtained from a quoted price in an active market, such securities are reflected within Level 2 of the fair value hierarchy.

The following is a summary of the inputs used as of May 31, 2013 in valuing the fund's investments:


	Short-Term
Valuation Inputs	Investments ($)^†
Level 1—Unadjusted Quoted Prices	—
Level 2—Other Significant Observable Inputs	260,456,443
Level 3—Significant Unobservable Inputs	—
Total	260,456,443
† See Statement of Investments for additional detailed categorizations.

At May 31, 2013, there were no transfers between Level 1 and Level 2 of the fair value hierarchy.

(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 is recognized on the accrual basis. Realized gains and losses from securities transactions are recorded on the identified cost basis. Cost of investments represents amortized cost.

The fund follows an investment policy of investing primarily in municipal obligations of one state. Economic changes affecting the state and certain of its public bodies and municipalities may affect the ability of issuers within the state to pay interest on, or repay principal of, municipal obligations held by the fund.

(c) Dividends to shareholders: It is policy of the fund to declare dividends daily from investment income-net. Such dividends are paid monthly. Dividends from net realized capital gains, 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 gains can be offset by capital loss carryovers, it is the policy of the fund not to distribute such gains.

The Fund 25

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

(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.

As of and during the period ended May 31, 2013, the fund did not have any liabilities for any uncertain tax positions.The fund recognizes interest and penalties, if any, related to uncertain tax positions as income tax expense in the Statement of Operations. During the period, the fund did not incur any interest or penalties.

Each tax year in the three-year period ended November 30, 2012 remains subject to examination by the Internal Revenue Service and state taxing authorities.

The tax character of distributions paid to shareholders during the fiscal year ended November 30, 2012 was as follows: tax-exempt income $44, ordinary income $407 and long-term capital gains $6,822. The tax character of current year distributions will be determined at the end of the current fiscal year.

At May 31, 2013, 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).

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.

The Manager has undertaken to waive receipt of the management fee and/or reimburse operating expenses in order to facilitate a daily yield at or above a certain level which may change from time to time.This

undertaking is voluntary and not contractual, and may be terminated at any time.The reduction in expenses, pursuant to the undertaking, amounted to $358,383 during the period ended May 31, 2013.

(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, 2013, the fund was charged $55,857 pursuant to the Shareholder Services Plan.

The fund has arrangements with the transfer agent and the custodian whereby the fund may receive earnings credits when positive cash balances are maintained, which are used to offset transfer agency and custody fees. For financial reporting purposes, the fund includes net earnings credits as an expense offset in the Statement of Operations.

The fund compensates Dreyfus Transfer, Inc., a wholly-owned subsidiary of the Manager, under a transfer agency agreement for providing transfer agency services for the fund and cash management services related to fund subscriptions and redemptions. During the period ended May 31, 2013, the fund was charged $24,783 for transfer agency services and $847 for cash management services. Cash management fees were partially offset by earnings credits of $142.These fees are included in Shareholder servicing costs in the Statement of Operations.

The fund compensates The Bank of New York Mellon, a subsidiary of BNY Mellon and an affiliate of Dreyfus, under a custody agreement for providing custodial services for the fund. During the period ended May 31, 2013, the fund was charged $13,945 pursuant to the custody agreement.

The Fund 27

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

The fund compensates The Bank of New York Mellon under a cash management agreement for performing certain cash management services related to fund subscriptions and redemptions.The Bank of New York Mellon also provides shareholder redemption draft processing services. During the period ended May 31, 2013, the fund was charged $550 pursuant to the cash management agreement, which is included in Shareholder servicing costs in the Statement of Operations. These fees were partially offset by earnings credits of $1.

During the period ended May 31, 2013, the fund was charged $4,558 for services performed by the Chief Compliance Officer and his staff.

The components of “Due to The Dreyfus Corporation and affiliates” in the Statement of Assets and Liabilities consist of: management fees $105,984, Shareholder Services Plan fees $9,000, custodian fees $6,405, Chief Compliance Officer fees $3,830 and transfer agency fees $8,637, which are offset against an expense reimbursement currently in effect in the amount of $61,369.

(d) 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.

NOTE 3—Securities Transactions:

The fund is permitted to purchase or sell securities from or to certain affiliated funds under specified conditions outlined in procedures adopted by the Board.The procedures have been designed to ensure that any purchase or sale of securities by the fund from or to another fund or portfolio that are, or could be, considered an affiliate by virtue of having a common investment adviser (or affiliated investment adviser), common Directors and/or common officers, complies with Rule 17a-7 under the Act. During the period ended May 31, 2013, the fund engaged in purchases and sales of securities pursuant to Rule 17a-7 under the Act amounting to $165,525,000 and $137,395,000, respectively.
