Dear Shareholder:

On the following pages, you’ll find your Fund’s semiannual report, including a table showing fund performance over the first half of the fiscal year and for longer periods. The report also contains a listing of the Fund’s holdings at period-end. The semiannual report is an interim statement furnished between the Fund’s annual reports, which include an analysis of Fund performance over the fiscal year in addition to other data.

Mutual fund prices and returns will rise or fall over time, and asset managers tend to have periods when they perform better or worse than their long-term average. The best measures of a mutual fund’s quality are its return compared to that of similar investments and the variability of its return over the long term. We recommend that you review your portfolio regularly with your financial professional.

Thank you for choosing JennisonDryden Mutual Funds.

Sincerely,

Judy A. Rice, President

Dryden Index Series Fund/Dryden Stock Index Fund

Your Fund’s Performance

Fund objective

The investment objective of the Dryden Stock Index Fund is to provide investment results that correspond to the price and yield performance of the Standard & Poor’s 500 Composite Stock Price Index (S&P 500 Index). There can be no assurance that the Fund will achieve its investment objective.

Performance data quoted represent past performance. Past performance does not guarantee future results. The investment return and principal value of an investment will fluctuate, so that an investor’s shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the past performance data quoted. An investor may obtain performance data as of the most recent month-end by visiting our website at www.jennisondryden.com or by calling (800) 225-1852. The maximum initial sales charge is 3.25% (Class A shares). Gross operating expenses: Class A, 0.80%; Class B, 1.86%; Class C, 1.81%; Class I, 0.44%; Class Z, 0.49%. Net operating expenses apply to: Class A, 0.58%; Class B, 1.64%; Class C, 1.59%; Class I, 0.22%; Class Z, 0.27%, after contractual reduction through 1/31/2010 for all classes.

The cumulative total returns do not reflect the deduction of applicable sales charges. If reflected, the applicable sales charges would reduce the cumulative total returns performance quoted. Class A shares are subject to a maximum front-end sales charge of 3.25%. Under certain circumstances, Class A shares may be subject to a contingent deferred sales charge (CDSC) of 1%. Class B and Class C shares are subject to a maximum CDSC of 5% and 1%, respectively. Class I and Class Z shares are not subject to a sales charge.

Source: Prudential Investments LLC and Lipper Inc. Performance figures may reflect fee waivers and/or expense reimbursements. In the absence of such fee waivers and/or expense reimbursements, total returns would be lower.

¹Inception date returns are provided for any share class with less than 10 calendar years of returns.

²The S&P 500 Index is an unmanaged index of 500 stocks of large U.S. public companies. It gives a broad look at how U.S. stock prices have performed.

³The Lipper EQ S&P 500 Index Objective Funds Average (Lipper Average) represents returns based on the average return of all funds in the Lipper EQ S&P 500 Index Objective Funds category for the periods noted. Funds in the Lipper Average are passively managed, limited expense (management fee no higher than 0.50%) funds designed to replicate the performance of the S&P 500 Index on a reinvested basis.

⁴The average annual total returns take into account applicable sales charges. Class A, Class B, and Class C shares are subject to an annual distribution and service (12b-1) fee of up to 0.30%, 1.00%, and 1.00%, respectively. Approximately seven years after purchase, Class B shares will automatically convert to Class A shares on a quarterly basis. Class I and Class Z shares are not subject to a 12b-1 fee. The returns in the tables do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or following the redemption of Fund shares.

**S&P 500 Index Closest Month-End to Inception cumulative total return is –32.25% for Class A, B, and C. S&P 500 Index Closest Month-End to Inception average annual total return is –4.09% for Class A, B, and C.

***Lipper Average Closest Month-End to Inception cumulative total return is –35.19% for Class A, B, and C. Lipper Average Closest Month-End to Inception average annual total return is –4.55% for Class A, B, and C.

Investors cannot invest directly in an index. The returns for the S&P 500 Index would be lower if they included the effects of sales charges, operating expenses of a mutual fund, or taxes. Returns for the Lipper Average reflect the deduction of operating expenses, but not sales charges or taxes.

Fees and Expenses (Unaudited)

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments and redemptions, as applicable, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses, as applicable. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested on October 1, 2008, at the beginning of the period, and held through the six-month period ended March 31, 2009. The example is for illustrative purposes only; you should consult the Prospectus for information on initial and subsequent minimum investment requirements.

The Fund’s transfer agent may charge additional fees to holders of certain accounts that are not included in the expenses shown in the table on the following page. These fees apply to individual retirement accounts (IRAs) and Section 403(b) accounts. As of the close of the six-month period covered by the table, IRA fees included an annual maintenance fee of $15 per account (subject to a maximum annual maintenance fee of $25 for all accounts held by the same shareholder). Section 403(b) accounts are charged an annual $25 fiduciary maintenance fee. Some of the fees may vary in amount, or may be waived, based on your total account balance or the number of JennisonDryden funds, including the Fund, that you own. You should consider the additional fees that were charged to your Fund account over the six-month period when you estimate the total ongoing expenses paid over the period and the impact of these fees on your ending account value, as these additional expenses are not reflected in the information provided in the expense table. Additional fees have the effect of reducing investment returns.

Actual Expenses

The first line for each share class in the table on the following page provides information about actual account values and actual expenses. You may use the information on this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value ÷ $1,000 = 8.6), then multiply the result by the number on the first line under the heading “Expenses Paid During the Six-Month Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line for each share class in the table on the following page provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before

Dryden Index Series Fund/Dryden Stock Index Fund 5

Fees and Expenses (continued)

expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs such as sales charges (loads). Therefore, the second line for each share class in the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

	Hypothetical	$	1,000.00	$	1,023.59	0.27	%	$	1.36

* Fund expenses (net of fee waivers or subsidies, if any) for each share class are equal to the annualized expense ratio for each share class (provided in the table), multiplied by the average account value over the period, multiplied by the 182 days in the six-month period ended March 31, 2009, and divided by the 365 days in the Fund’s fiscal year ending September 30, 2009 (to reflect the six-month period). Expenses presented in the table include the expenses of any underlying portfolios in which the Fund may invest.

Dryden Index Series Fund/Dryden Stock Index Fund 31

Notes to Financial Statements

(Unaudited)

The Dryden Index Series Fund (the “Company”) is registered under the Investment Company Act of 1940, as amended, as an open-end, diversified management investment company. The Company was established as a Delaware business trust on May 11, 1992 and currently consists of one fund, which is the Dryden Stock Index Fund (the “Fund”). Investment operations of the Fund commenced on November 5, 1992. The Fund’s investment objective is to provide investment results that correspond to the price and yield performance of Standard & Poor’s 500 Composite Stock Price Index.

Note 1. Accounting Policies

The following is a summary of significant accounting policies followed by the Fund in preparation of its financial statements.

Securities Valuation: Securities listed on a securities exchange (other than options on securities and indices) are valued at the last sale price on such exchange on the day of valuation or, if there was no sale on such day, at the mean between the last reported bid and ask prices, or at the last bid price on such day in the absence of an asked price. Securities traded via NASDAQ are valued at the NASDAQ official closing price (NOCP) on the day of valuation, or if there was no NOCP, at the last sale price.

Securities that are actively traded in the over-the-counter market, including listed securities for which the primary market is believed by Prudential Investments LLC (“PI” or “Manager”), in consultation with the subadviser(s); to be over-the-counter, are valued at market value using prices provided by an independent pricing agent or principal market maker. Options on securities and indices traded on an exchange are valued at the last sale price as of the close of trading on the applicable exchange or, if there was no sale, at the mean between the most recently quoted bid and asked prices on such exchange. Futures contracts and options thereon traded on a commodities exchange or board of trade are valued at the last sale price at the close of trading on such exchange or board of trade or, if there was no sale on the applicable commodities exchange or board of trade on such day, at the mean between the most recently quoted bid and asked prices on such exchange or board of trade or at the last bid price in the absence of an asked price. Securities for which reliable market quotations are not readily available, or whose values have been affected by events occurring after the close of the security’s foreign market and before

the Fund’s normal pricing time, are valued at fair value in accordance with the Board of Trustees’ approved fair valuation procedures. When determining the fair valuation of securities some of the factors influencing the valuation include, the nature of any restrictions on disposition of the securities; assessment of the general liquidity of the securities; the issuer’s financial condition and the markets in which it does business; the cost of the investment; the size of the holding and the capitalization of issuer; the prices of any recent transactions or bids/offers for such securities or any comparable securities; any available analyst media or other reports or information deemed reliable by the investment adviser regarding the issuer or the markets or industry in which it operates. Using fair value to price securities may result in a value that is different from a security’s most recent closing price and from the price used by other mutual funds to calculate their net asset values.

Investments in mutual funds are valued at their net asset value as of the close of the New York Stock Exchange on the date of valuation.

Short-term debt securities which mature in 60 days or less are valued at amortized cost, which approximates market value. The amortized cost method involves valuing a security at its cost on the date of purchase and thereafter assuming a constant amortization to maturity of the difference between the principal amount due at maturity and cost. Short-term debt securities which mature in more than 60 days are valued at current market quotations.

Financial Futures Contracts: A financial futures contract is an agreement to purchase (long) or sell (short) an agreed amount of securities at a set price for delivery on a future date. Upon entering into a financial futures contract, the Fund is required to pledge to the broker an amount of cash and/or other assets equal to a certain percentage of the contract amount. This amount is known as the “initial margin.” Subsequent payments, known as “variation margin,” are made or received by the Fund each day, depending on the daily fluctuations in the value of the underlying security. Such variation margin is recorded for financial statement purposes on a daily basis as unrealized gain or loss. When the contract expires or is closed, the gain or loss is realized and is presented in the Statement of Operations as net realized gain or loss on financial futures contracts. The Fund invests in financial futures contracts in order to hedge its existing portfolio securities, or securities the Fund intends to purchase, against fluctuations in value caused by changes in prevailing interest rates or market conditions. Should interest rates move unexpectedly, the Fund may not achieve the anticipated benefits of the financial futures contracts and may realize a loss. The use of futures transactions involves the risk of imperfect correlation in movements in the price of futures contracts, interest rates and the underlying hedged assets.

Risk: Financial futures contracts involve elements of both market and credit risk in excess of the amounts reflected on the Statement of Assets and Liabilities.

Securities Lending: The Fund may lend its portfolio securities to broker-dealers. The loans are secured by collateral at least equal, at all times, to the market value of the securities loaned. Loans are subject to termination at the option of the borrower or the Fund. Upon termination of the loan, the borrower will return to the lender securities identical to the loaned securities. Should the borrower of the securities fail financially, the Fund has the right to repurchase the securities using the collateral in the open market. The Fund recognizes income, net of any rebate and securities lending agent fees, for lending its securities in the form of fees or interest on the investment of any cash received as collateral. The Fund also continues to receive interest and dividends or amounts equivalent thereto, on the securities loaned and recognizes any unrealized gain or loss in the market price of the securities loaned that may occur during the term of the loan.

Securities Transactions and Net Investment Income: Securities transactions are recorded on the trade date. Realized and unrealized gains or losses on sales of securities are calculated on the identified cost basis. Dividend income is recorded on the ex-dividend date and interest income, including amortization of premium and accretion of discount on debt securities, as required, is recorded on the accrual basis. Expenses are recorded on the accrual basis.

Net investment income or loss (other than distribution and transfer agent fees) and unrealized and realized gains or losses are allocated daily to each class of shares based upon the relative proportion of net assets of each class at the beginning of the day. Transfer agent fees are incurred based on shareholder activity and number of accounts for each class.

Dividends and Distributions: Dividends from net investment income and distributions from net capital and currency gains in excess of a capital loss carryforward, if any, are declared and paid annually. Dividends and distributions to shareholders, which are determined in accordance with federal income tax regulations which may differ from generally accepted accounting principles, are recorded on the ex-dividend date. Permanent book/tax differences relating to income and gains are reclassified amongst undistributed net investment income, accumulated net realized gain or loss and paid in capital in excess of par, as appropriate.

Taxes: It is the Fund’s policy to continue to meet the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable net income and net capital gains, if any, to its shareholders. Therefore, no federal income tax provision is required.

Withholding taxes on foreign dividends have been provided for in accordance with the Fund’s understanding of the applicable country’s tax rules and rates.

Estimates: The preparation of the financial statements requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates.

Note 2. Agreements

The Fund has a management agreement with PI. Pursuant to this agreement, PI has responsibility for all investment advisory services and supervises the subadviser’s performance of such services. PI has entered into a subadvisory agreement with Quantitative Management Associates LLC (“QMA”). The subadvisory agreement provides that QMA furnishes investment advisory services in connection with the management of the Fund. In connection therewith, QMA is obligated to keep certain books and records of the Fund. PI pays for the services of QMA, the cost of compensation of officers of the Fund, occupancy and certain clerical and bookkeeping costs of the Fund. The Fund bears all other costs and expenses.

The management fee paid to PI is computed daily and payable monthly at an annual rate of .30 of 1% of the average daily net assets of the Fund up to $1 billion and .25 of 1% in excess of $1 billion. Effective June 1, 2007 to January 31, 2010, the Fund’s manager has agreed to contractually waive a portion of its management fee, so that the effective management fee for the Fund will be .08 of 1% of the average daily net assets of Fund. The effective management fee rate was .08 of 1% of the average daily net assets for the six months ended March 31, 2009.

The Fund has a distribution agreement with Prudential Investment Management Services LLC (“PIMS”), which acts as the distributor of the Class A, Class B, Class C, Class I and Class Z shares of the Fund. The Fund compensates PIMS for distributing and servicing the Fund’s Class A, Class B and Class C shares, pursuant to plans of distribution, (the “Class A, B and C plans”), regardless of expenses actually incurred by PIMS. The distribution fees are accrued daily and payable monthly. No distribution or service fees are paid to PIMS as distributor for Class I and Class Z shares of the Fund.

(Unaudited) continued

Pursuant to the Class A, B and C Plans, the Fund compensates PIMS for distribution- related activities at an annual rate of up to .30 of 1%, 1% and 1% of the average daily net assets of the Class A, B and C shares, respectively.

PIMS has advised the Fund that it received approximately $36,000 in front-end sales charges resulting from sales of Class A shares during the six months ended March 31, 2009. From these fees, PIMS paid sales charges to dealers who in turn paid commissions to salespersons, and incurred other distribution costs.

PIMS has advised the Fund that for the six months ended March 31, 2009, it received approximately $21,000 and $1,000 in contingent deferred sales charges imposed upon certain redemptions by Class B and Class C shareholders, respectively.

PI, QMA and PIMS are indirect, wholly-owned subsidiaries of Prudential Financial, Inc. (“Prudential”).

The Fund, along with other affiliated registered investment companies (the “Funds”), is a party to a Syndicated Credit Agreement (“SCA”) with two banks. The SCA provides for a commitment of $500 million. Interest on any borrowings under the SCA is incurred at contracted market rates and a commitment fee for the unused amount is accrued daily and paid quarterly. Effective October 24, 2008, the Funds renewed the SCA with the banks. The commitment under the renewed SCA continues to be $500 million. The Funds pay a commitment fee of .13 of 1% of the unused portion of the renewed SCA. The expiration date of the renewed SCA will be October 23, 2009. For the period from October 26, 2007 through October 23, 2008, the Funds paid a commitment fee of .06 of 1% of the unused portion of the agreement. The purpose of the SCA is to provide an alternative source of temporary funding for capital share redemptions.

The Fund did not borrow any amounts pursuant to the SCA during the six months ended March 31, 2009.

Note 3. Other Transactions with Affiliates

Prudential Mutual Fund Services LLC (“PMFS”), an affiliate of PI and an indirect, wholly-owned subsidiary of Prudential, serves as the Fund’s transfer agent. Transfer agent fees and expenses in the Statement of Operations include certain out-of-pocket

36 Visit our website at www.jennisondryden.com

expenses paid to non-affiliates, where applicable. The Fund’s Class I and Class Z shares are subject to a transfer agent fee of .07% and .13% of the average daily net assets of the Class I and Class Z shares, respectively. Classes A, B, and C each compensate PMFS for its services as they are incurred.

The Fund pays networking fees to affiliated and unaffiliated broker/dealers including fees relating to the services of First Clearing, LLC (“First Clearing”), an affiliate of PI. These networking fees are payments made to broker/dealers that clear mutual fund transactions through a national clearing system. For the six months ended March 31, 2009, the Fund incurred approximately $50,400 in total networking fees of which approximately $32,100 was paid to First Clearing. These amounts are included in transfer agent’s fees and expenses in the Statement of Operations.

Prudential Investment Management Inc. (“PIM”), an indirect, wholly-owned subsidiary of Prudential, is the Fund’s security lending agent. For the six months ended March 31, 2009, PIM has been compensated approximately $199,300 for these services.

The Fund invests in the Taxable Money Market Series (the “Portfolio”), a portfolio of the Dryden Core Investment Fund. The Portfolio is a money market mutual fund registered under the Investment Company Act of 1940, as amended, and managed by PI.

Note 4. Portfolio Securities

Purchases and sales of portfolio securities, excluding short-term investments, for the six months ended March 31, 2009 aggregated $23,532,099 and $75,611,009 respectively.

Note 5. Tax Information

For federal income tax purposes, the Fund had a capital loss carryforward as of September 30, 2008 of approximately $114,571,000 of which $64,426,000 expires in 2011, $1,967,000 expires in 2012, $16,903,000 expires in 2013 and $31,275,000 expires in 2014. The Fund utilized approximately $55,102,000 of its capital loss carryforward during fiscal year ended September 30, 2008. Accordingly, no capital gains distribution is expected to be paid to shareholders until net gains have been realized in excess of this amount. It is uncertain whether the Fund will be able to realize the full benefit prior to the expiration date.

Notes to Financial Statements

(Unaudited) continued

The United States federal income tax basis of the Fund’s investments and the net unrealized appreciation as of March 31, 2009 were as follows:

Tax Basis of Investments	Appreciation	Depreciation	Net Unrealized Appreciation
$657,151,792	$221,397,527	$(154,740,255)	$66,657,272

The difference between book basis and tax basis was primarily attributable to deferred losses on wash sales.

Management has analyzed the Fund’s tax positions taken on federal income tax returns for all open tax years and has concluded that as of March 31, 2009, no provision for income tax would be required in the Fund’s financial statements. The Fund’s federal and state income and federal excise tax returns for tax years for which the applicable statutes of limitations have not expired are subject to examination by the Internal Revenue Service and state departments of revenue.

Note 6. Capital

The Fund offers Class A, Class B, Class C, Class I and Class Z shares. Class A shares are sold with a front-end sales charge of up to 3.25%. Certain investors who purchase $1 million or more of Class A shares and sell these shares within 12 months of purchase are subject to a 1% contingent deferred sales charge, although they are not subject to an initial sales charge. Class B shares are sold with a contingent deferred sales charge (CDSC) which declines from 5% to zero depending upon the period of time the shares are held. Class C shares are sold with a CDSC of 1% during the first year. Class B shares will automatically convert to Class A shares on a quarterly basis approximately seven years after purchase. Class B shares are not available for purchase by new investors. Class I and Class Z shares are not subject to any sales or redemption charge and are offered exclusively for sale to a limited group of investors.

The Fund has authorized an unlimited number of shares of beneficial interest at $.001 par value divided into five classes, designated Class A, Class B, Class C, Class I and Class Z.

Note 8. New Accounting Pronouncement

In March 2008, the Financial Accounting Standard Board (“FASB”) released Statement of Financial Accounting Standards No. 161, “Disclosures about Derivative Instruments and Hedging Activities” (“FAS 161”). FAS 161 requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements. The application of FAS 161 is required for any reporting period beginning after November 15, 2008. At this time, management is evaluating the implications of FAS 161 and its impact on the financial statements has not yet been determined.

In April 2009, the FASB issued FASB Staff Position 157-4, “Determining Fair Value When the Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly” (“FSP 157-4”) and is effective for interim and annual periods ending after June 15, 2009. FSP 157-4 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. The FSP also indicates that entities should consider and evaluate the impact of decreased market activity and whether transactions are orderly in arriving at a fair value for its assets and liabilities, including evaluating whether values provided by pricing services are based on current information that reflects orderly transactions. FSP 157-4 requires enhanced disclosures around valuation inputs and techniques used during annual and interim periods. Management is currently evaluating the impact the adoption of FSP 157-4 will have on the Fund’s financial statement disclosures.
