A LETTER FROM THE PRESIDENT

Dear Shareholder:

We are pleased to present this annual report for Dreyfus Midcap Index Fund, Inc., covering the 12-month period from November 1, 2013, through October 31, 2014. 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.

Despite bouts of heightened volatility stemming mainly from economic and geopolitical concerns in overseas markets, U.S. stocks gained ground over the reporting period as the domestic economy continued to rebound. As a result, several broad measures of equity market performance established new record highs. Smaller and more economically sensitive stocks generally fared well over the reporting period’s first half, but larger, better established companies rallied more strongly over the second half.

We remain cautiously optimistic regarding the U.S. stock market’s prospects. We currently expect the economy to continue to accelerate as several longstanding drags—including tight fiscal policies and private sector deleveraging—fade from the scene. Of course, a number of risks remain, including the possibilities of higher interest rates and intensifying geopolitical turmoil. As always, we encourage you to discuss our observations with your financial adviser to assess their potential impact on your investments.

Thank you for your continued confidence and support.

J. Charles Cardona
President
The Dreyfus Corporation

DISCUSSION OF FUND PERFORMANCE

For the period of November 1, 2013, through October 31, 2014, as provided by Thomas J. Durante, CFA, Karen Q.Wong, CFA, and Richard A. Brown, CFA, Portfolio Managers

Fund and Market Performance Overview

For the 12-month period ended October 31, 2014, Dreyfus Midcap Index Fund produced a total return of 11.21%.¹ The Standard & Poor’s MidCap 400^® Index (“S&P 400 Index”), the fund’s benchmark, produced a total return of 11.65% for the same period.^2,3

Despite bouts of occasional volatility, sustained improvement in U.S. economic conditions generally helped support stock market gains across all capitalization ranges over the reporting period overall.The difference in returns between the fund and the S&P 400 Index was primarily the result of transaction costs and operating expenses that are not reflected in the S&P 400 Index’s results.

The Fund’s Investment Approach

The fund seeks to match the total return of the S&P 400 Index by generally investing in all 400 stocks in the S&P 400 Index, in proportion to their respective weightings. The fund may also use stock index futures as a substitute for the sale or purchase of stocks.The S&P 400 Index is composed of 400 stocks of midsize domestic companies across 10 economic sectors. Each stock is weighted by its market capitalization; that is, larger companies have greater representation in the S&P 400 Index than smaller ones.

The fund employed futures contracts during the reporting period in its efforts to replicate the returns of the S&P 400 Index.

Stocks Climbed Despite Bouts of Volatility

The S&P 400 Index and other broad measures of stock market performance gained value over the final months of 2013 amid falling unemployment and intensifying manufacturing activity.The Federal Reserve Board (the “Fed”) appeared to confirm the economic recovery’s sustainability in December, when it began to back gradually away from its quantitative easing program. Stocks gave up some of their previous gains in January, when concerns arose regarding economic and political instability in

the emerging markets. In addition, U.S. GDP contracted at a surprising annualized 2.1% rate over the first quarter of 2014 due to the dampening effects of severe winter weather on corporate spending, housing market activity, export activity, and business inventory accumulation.

U.S. stocks soon rebounded strongly, with the S&P 400 Index climbing to new highs through the beginning of July as investors responded positively to expectations that the Fed would keep short-term interest rates low even as labor markets, manufacturing activity, consumer confidence, and other economic indicators improved. In fact, the U.S. economy rebounded at a robust 4.6% annualized rate during the second quarter of the year.

The market encountered renewed volatility in July and September, when disappointing economic growth in Europe, China, and Japan sparked concerns that a weaker-than-expected global economy might derail the U.S. expansion. However, strong corporate earnings and solid domestic economic data—including an estimated 3.5% annualized GDP growth rate for the third quarter of 2014—enabled the S&P 400 Index to recoup many of its more recent losses by the reporting period’s end.

In this environment, midcap stocks produced higher returns, on average, than their small-cap counterparts, but they generally lagged large-cap stocks.

Financial and Health Care Stocks Led Market’s Advance

Nine of the 10 economic segments represented in the S&P 400 Index posted positive absolute returns over the reporting period. Results were especially robust in the financials sector, where real estate investment trusts (REITs) gained value amid greater demand from income-oriented investors seeking competitive yields from dividend-paying stocks in a low interest-rate environment. REITs specializing in urban office space and retail strip malls fared especially well. Midsize insurance companies also gained value as home sales and mergers-and-acquisitions activity intensified.

In the health care sector, hospitals and health maintenance organizations (HMOs) benefited from fewer uninsured patients and rising enrollment trends, respectively, after full implementation of the Affordable Care Act. Veterinary clinics achieved higher revenues as pet owners’ disposable income increased. Pharmaceutical developers reported strong sales growth in the emerging markets, and medical equipment

producers saw better-than-expected sales amid rising demand despite recent tax increases on their products. In the information technology sector, semiconductor equipment makers and suppliers to mobile phone manufacturers benefited from robust consumer demand for new smartphones, while solar energy equipment producers saw rising sales in China and India.

On the other hand, the energy sector generally declined due to weak results from offshore drillers and other service providers in an environment of falling oil prices and weak economic conditions in international markets. The telecommunications services sector lagged market averages due to weakness among fixed-line telephone service providers.

Replicating the Performance of the S&P 400 Index

Although we do not actively manage the fund’s investments in response to macroeconomic trends, it is worth noting that the U.S. economic recovery appears to remain on track.As always, we have continued to monitor the factors considered by the fund’s investment model in light of current market conditions.

NOTES TO FINANCIAL STATEMENTS

NOTE 1—Significant Accounting Policies:

Dreyfus Midcap Index 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 seeks to match the performance of the Standard & Poor’s^® MidCap 400 Index. 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.

The Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 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.

(a) Portfolio valuation: 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).

The Fund 27

NOTES TO FINANCIAL STATEMENTS (continued)

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.

Changes in valuation techniques may result in transfers in or out of an assigned level within the disclosure hierarchy. Valuation techniques used to value the fund’s investments are as follows:

Investments in securities are valued at the last sales price on the securities exchange or national securities market on which such securities are primarily traded. Securities listed on the National Market System for which market quotations are available are valued at the official closing price or, if there is no official closing price that day, at the last sales price. Securities not listed on an exchange or the national securities market, or securities for which there were no transactions, are valued at the average of the most recent bid and asked prices, except for open short positions, where the asked price is used for valuation purposes. Bid price is used when no asked price is available. Registered investment companies that are not traded on an exchange are valued at their net asset value.All of the preceding securities are generally categorized within Level 1 of the fair value hierarchy.

28

U.S. Treasury Bills are valued at the mean price between quoted bid prices and asked prices by an independent pricing service (the “Service”) approved by the fund’s Board of Directors (the “Board”). These securities are generally categorized within Level 2 of the fair value hierarchy.

The Service’s procedures are reviewed by Dreyfus under the general supervision of the Board.

Fair valuing of securities may be determined with the assistance of a pricing service using calculations based on indices of domestic securities and other appropriate indicators, such as prices of relevant American Depository Receipts and financial futures. Utilizing these techniques may result in transfers between Level 1 and Level 2 of the fair value hierarchy.

When market quotations or official closing prices are not readily available, or are determined not to reflect accurately fair value, such as when the value of a security has been significantly affected by events after the close of the exchange or market on which the security is principally traded (for example, a foreign exchange or market), but before the fund calculates its net asset value, the fund may value these investments at fair value as determined in accordance with the procedures approved by the Board. Certain factors may be considered when fair valuing investments such as: fundamental analytical data, the nature and duration of restrictions on disposition, an evaluation of the forces that influence the market in which the securities are purchased and sold, and public trading in similar securities of the issuer or comparable issuers. These securities are either categorized within Level 2 or 3 of the fair value hierarchy depending on the relevant inputs used.

For restricted securities where observable inputs are limited, assumptions about market activity and risk are used and are generally categorized within Level 3 of the fair value hierarchy.

Financial futures, which are traded on an exchange, are valued at the last sales price on the securities exchange on which such securities are

The Fund 29

NOTES TO FINANCIAL STATEMENTS (continued)

primarily traded or at the last sales price on the national securities market on each business day and are generally categorized within Level 1 of the fair value hierarchy.

The following is a summary of the inputs used as of October 31, 2014 in valuing the fund’s investments:

		Level 2—Other	Level 3—
	Level 1—	Significant	Significant
	Unadjusted	Observable	Unobservable

At October 31, 2014, 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. Realized gains and losses from securities transactions are recorded on the identified cost basis. Dividend income is recognized on the ex-dividend date and interest income, including, where applicable, accretion of discount and amortization of premium on investments, is recognized on the accrual basis.

Pursuant to a securities lending agreement with The Bank of New York Mellon, a subsidiary of BNY Mellon and an affiliate of Dreyfus,

30

the fund may lend securities to qualified institutions. It is the fund’s policy that, at origination, all loans are secured by collateral of at least 102% of the value of U.S. securities loaned and 105% of the value of foreign securities loaned. Collateral equivalent to at least 100% of the market value of securities on loan is maintained at all times. Collateral is either in the form of cash, which can be invested in certain money market mutual funds managed by the Manager or U.S. Government and Agency securities. The fund is entitled to receive all dividends, interest and distributions on securities loaned, in addition to income earned as a result of the lending transaction. Should a borrower fail to return the securities in a timely manner, The Bank of New York Mellon is required to replace the securities for the benefit of the fund or credit the fund with the market value of the unreturned securities and is subrogated to the fund’s rights against the borrower and the collateral. During the period ended October 31, 2014,The Bank of New York Mellon earned $488,625 from lending portfolio securities, pursuant to the securities lending agreement.

(c) Affiliated issuers: Investments in other investment companies advised by Dreyfus are defined as “affiliated” under the Act. Investments in affiliated investment companies during the period ended October 31, 2014 were as follows:

NOTES TO FINANCIAL STATEMENTS (continued)

(d) Dividends to shareholders: Dividends are recorded on the ex-dividend date. Dividends from investment income-net and 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. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

(e) Federal income taxes: It is the policy of the fund to continue to qualify as a regulated investment company, if such qualification is in the best interests of its shareholders, by complying with the applicable provisions of the Code, and to make distributions of taxable income sufficient to relieve it from substantially all federal income and excise taxes.

As of and during the period ended October 31, 2014, 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 ended October 31, 2014, the fund did not incur any interest or penalties.

Each tax year in the four-year period ended October 31, 2014 remains subject to examination by the Internal Revenue Service and state taxing authorities.

At October 31, 2014, the components of accumulated earnings on a tax basis were as follows: undistributed ordinary income $31,649,427, undistributed capital gains $187,117,220 and unrealized appreciation $1,253,908,896.

The tax character of distributions paid to shareholders during the fiscal periods ended October 31, 2014 and October 31, 2013 were as follows: ordinary income $43,050,248 and $32,853,514, and long-term capital gains $112,815,059 and $90,037,003, respectively.

NOTE 2—Bank Lines of Credit:

The fund participates with other Dreyfus-managed funds in a $430 million unsecured credit facility led by Citibank, N.A. and a $300 million unsecured credit facility provided by The Bank of New York Mellon (each, a “Facility”), each to be utilized primarily for temporary or emergency purposes, including the financing of redemptions. Prior to October 8, 2014, the unsecured credit facility with Citibank, N.A. was $265 million. In connection therewith, the fund has agreed to pay its pro rata portion of commitment fees for each Facility. Interest is charged to the fund based on rates determined pursuant to the terms of the respective Facility at the time of borrowing.

The average amount of borrowings outstanding under the Facilities during the period ended October 31, 2014 was approximately $716,200 with a related weighted average annualized interest rate of 1.09%.

NOTE 3—Management Fee and Other Transactions with Affiliates:

(a) Pursuant to a management agreement (the “Agreement”) with the Manager, the management fee is computed at the annual rate of .25% of the value of the fund’s average daily net assets and is payable monthly. Under the terms of the Agreement, the Manager has agreed to pay all of the fund’s direct expenses, except management fees, Shareholder Services Plan fees, brokerage fees and commissions, taxes, interest expense, commitment fees on borrowings, fees and expenses of non-interested Board members, fees and expenses of independent counsel to the fund and extraordinary expenses. The Manager has also agreed to reduce its management fee in an amount equal to the fund’s allocable portion of the accrued fees and expenses of the non-interested Board members and fees and expenses of independent counsel to the fund and to non-interested Board members. During the period ended October 31, 2014, fees reimbursed by the Manager amounted to $246,159.

The Fund 33

NOTES TO FINANCIAL STATEMENTS (continued)

(b) Under the Shareholder Services Plan, the fund pays the Distributor for the provision of certain services, at an annual rate of .25% of the value of the fund’s average daily net assets.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.The Distributor may make payments to Service Agents (securities dealers, financial institutions or other industry professionals) with respect to these services.The Distributor determines the amounts to be paid to Service Agents. During the period ended October 31, 2014, the fund was charged $8,851,384 pursuant to the Shareholder Services Plan.

The components of “Due to The Dreyfus Corporation and affiliates” in the Statement of Assets and Liabilities consist of: management fees $721,342 and Shareholder Services Plan fees $721,342, which are offset against an expense reimbursement currently in effect in the amount of $18,852.

(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.

NOTE 4—Securities Transactions:

The aggregate amount of purchases and sales of investment securities, excluding short-term securities and financial futures, during the period ended October 31, 2014, amounted to $568,751,610 and $674,299,968, respectively.

Derivatives: A derivative is a financial instrument whose performance is derived from the performance of another asset. Each type of derivative instrument that was held by the fund during the period ended October 31, 2014 is discussed below.

Financial Futures: In the normal course of pursuing its investment objective, the fund is exposed to market risk, including equity price risk as a result of changes in value of underlying financial instruments.The

34

fund invests in financial futures in order to manage its exposure to or protect against changes in the market. A financial futures contract represents a commitment for the future purchase or a sale of an asset at a specified date. Upon entering into such contracts, these investments require initial margin deposits with a counterparty, which consist of cash or cash equivalents.The amount of these deposits is determined by the exchange or Board of Trade on which the contract is traded and is subject to change. Accordingly, variation margin payments are received or made to reflect daily unrealized gains or losses which are recorded in the Statement of Operations.When the contracts are closed, the fund recognizes a realized gain or loss which is reflected in the Statement of Operations.There is minimal counterparty credit risk to the fund with financial futures since they are exchange traded, and the exchange guarantees the financial futures against default. Financial futures open at October 31, 2014 are set forth in the Statement of Financial Futures.

The following summarizes the average market value of derivatives outstanding during the period ended October 31, 2014:

	Average Market Value ($)
Equity financial futures	40,047,970

At October 31, 2014, the cost of investments for federal income tax purposes was $2,470,722,677; accordingly, accumulated net unrealized appreciation on investments was $1,253,908,896, consisting of $1,358,820,943 gross unrealized appreciation and $104,912,047 gross unrealized depreciation.

NOTE 5—Pending Legal Matters

The fund and dozens of other entities and individuals have been named as defendants in an adversary proceeding pending in the United States Bankruptcy Court for the Southern District of New York (Weisfelner, as Trustee of the LB Creditor Trust v. Fund 1, et al., Adv. Pro. No. 10-04609).The complaint alleges that payments made to shareholders

of Lyondell Chemical Company (“Lyondell”) in connection with the acquisition of Lyondell by Basell AF S.C.A. in a cash-out merger in or around December, 2007 constitute constructive or intentional “fraudulent transfers” under applicable state law and seeks to recover from the former Lyondell shareholders the payments received for the shares.

On January 14, 2014, the Court issued a decision and order on motions to dismiss granting in part, and denying in part, the motions. On April 9, 2014, plaintiff filed a Third Amended Complaint continuing to assert constructive or intentional fraudulent transfer claims under applicable state law.

At this stage in the proceedings, it is not possible to assess with any reasonable certainty the probable outcome of the pending litigation. Consequently, at this time, management is unable to estimate the possible loss that may result.

PUBLIC ACCOUNTING FIRM 

Shareholders and Board of Directors
Dreyfus Midcap Index Fund, Inc.

We have audited the accompanying statement of assets and liabilities of Dreyfus Midcap Index Fund, Inc., including the statements of investments and financial futures, as of October 31, 2014, 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 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. 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 as of October 31, 2014 by correspondence with the custodian and others.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 Midcap Index Fund, Inc. at October 31, 2014, 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 five years in the period then ended, in conformity with U.S. generally accepted accounting principles.
