PROSPECTUS

245,711 Shares
EQUITY RESIDENTIAL
Common Shares of Beneficial Interest

     This prospectus relates solely to the offer and sale from time to time of up to 245,711 of our common shares of beneficial interest (“Common Shares”) by the persons listed below, who are, or may become, shareholders of Equity Residential. In this prospectus we refer to these persons as the Selling Shareholders. We may issue such Common Shares to the Selling Shareholders, upon their request, in exchange for their units of limited partnership interest in ERP Operating Limited Partnership, our operating partnership.

     The Selling Shareholders may offer their common shares through public or private transactions, on or off the New York Stock Exchange, at prevailing market prices, or at privately negotiated prices. The Selling Shareholders may sell their Common Shares directly or through agents or broker-dealers acting as principal or agent, or in a distribution by underwriters.

     We are registering the Common Shares to permit the holders to sell without restriction in the open market or otherwise, but the registration of these Common Shares does not necessarily mean that any holders will elect to exchange their units of limited partnership interest in our operating partnership or offer or sell any of these Common Shares. Also, we may elect to pay cash for the units of our operating partnership tendered rather than issue Common Shares. Although we will incur expenses in connection with the registration of the 245,711 Common Shares, we will not receive any cash proceeds upon their issuance.

     The Common Shares are listed on the New York Stock Exchange under the symbol “EQR”.

     Investing in our securities involves risk. Before buying our securities, you should read and consider the risk factors included in our periodic reports and in other information that we file with the Securities and Exchange Commission. See “Special Note Regarding Forward-Looking Statements.”

     Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus. Any representation to the contrary is a criminal offense.

The date of this prospectus is July        , 2011.

Unless otherwise indicated, when used herein, the terms “we” and “us” refer to Equity Residential, a Maryland real estate investment trust, and its subsidiaries, including ERP Operating Limited Partnership, its operating partnership.

THE COMPANY

     We are a Maryland real estate investment trust (“REIT”) formed in March 1993 and are an S&P 500 company focused on the acquisition, development and management of high quality apartment properties in top United States growth markets. We have elected to be taxed as a REIT.

     We are one of the largest publicly traded real estate companies and the largest publicly traded owner of multifamily properties in the United States of America (based on the aggregate market value of our outstanding common shares, the number of apartment units wholly owned and total revenues earned). Our corporate headquarters are located in Chicago, Illinois and we also operate property management offices in each of our markets.

     Our executive offices are located at Two North Riverside Plaza, Suite 400, Chicago, Illinois 60606, and our telephone number is (312) 474-1300.

NO PROCEEDS TO THE COMPANY

     We will not receive any of the proceeds from the sale of Common Shares by Selling Shareholders. We will pay all of the costs and expenses incurred in connection with the registration under the Securities Act of the offering made hereby. Notwithstanding the previous sentence, any brokerage fees and commissions, fees and disbursements of legal counsel for the Selling Shareholders and share transfer and other taxes attributable to the issuance by us of the Common Shares will be paid by the Selling Shareholders.

SELLING SHAREHOLDERS

     We may issue up to 245,711 Common Shares to the Selling Shareholders if and to the extent that the Selling Shareholders who currently hold units of limited partnership interest in our operating partnership (“Units”) exchange their Units and we issue Common Shares to them in exchange therefor. Following our issuance of any of the offered Common Shares, the Selling Shareholders may resell the Common Shares covered by this prospectus as provided under the Plan of Distribution section of this prospectus or as described in an applicable prospectus supplement.

     The following table sets forth the name of each Selling Shareholder and the maximum number of Common Shares to be owned upon exchange of Units, all of which may be offered by such Selling Shareholders pursuant to this prospectus. The number of Common Shares set forth in the following table is also the number of Common Shares beneficially owned by each selling shareholder prior to the offering, except as otherwise set forth therein. Because the Selling Shareholders may sell all or some of their offered Common Shares, no estimate can be made of the number of offered Common Shares that will be sold by the Selling Shareholders or that will be owned by the Selling Shareholders upon completion of the offering. We cannot assure you that the Selling Shareholders will sell any of the offered Common Shares. In addition, we may elect to pay cash for any Units exchanged, rather than exchanging those Units for Common Shares. The Common Shares covered by this prospectus represent less than one percent of the total Common Shares outstanding as of March 31, 2011.

ADDITIONAL FEDERAL INCOME TAX CONSIDERATIONS

     The following discussion supplements the discussion under the heading “Federal Income Tax Considerations” in our annual report on Form 10-K for the year ended December 31, 2010, which has been incorporated into this prospectus by reference. The following discussion summarizes the material federal income tax considerations that may be relevant to a Selling Shareholder who desires to have its Units exchanged for Common Shares.

     Tax Treatment of an Exchange of Units.If a Selling Shareholder exchanges Units of limited partnership interest in our operating partnership for Common Shares, the exchange will be a taxable event and, as a result, the Selling Shareholder will recognize gain or loss. The determination of the amount of gain or loss that will be recognized by a Selling Shareholder will be based on the difference between the amount realized for tax purposes and the tax basis in the Selling Shareholder’s Units. See “Basis of Units” below. The “amount realized” will be equal to the product of (i) the number of Units exchanged, multiplied by the price of the Common Shares received on the date of the exchange plus (ii) the portion of our operating partnership’s liabilities allocable to the Units exchanged. To the extent that this amount exceeds the Selling Shareholder’s tax basis in the Units exchanged, the Selling Shareholder will recognize gain. The amount of gain the Selling Shareholder recognizes could exceed the value of the Common Shares that the Selling Shareholder receives if the Selling Shareholder has a “negative tax capital account.” It is even possible that the tax liability resulting from this gain could exceed the value of the Common Shares that the Selling Shareholder receives.

     Except as described below, any gain recognized upon a sale or other disposition of Units, which includes the exchange of Units for Common Shares, will be treated as gain attributable to the sale or disposition of a capital asset. To the extent, however, that the amount realized by a Selling Shareholder in an exchange of Units for Common Shares attributable to a Selling Shareholder’s share of “unrealized receivables” of our operating partnership exceeds the Selling Shareholder’s basis attributable to the “unrealized receivables”, the excess will be treated as ordinary income. Unrealized receivables include, to the extent not previously included in our operating partnership’s income, any rights to payments for services rendered or to be rendered. Unrealized receivables also include amounts that would be subject to recapture as ordinary income if our operating partnership had sold its assets at their fair market value at the time of the transfer of the Units.

     For individuals, trusts and estates, net capital gain from the sale of an asset held 12 months or less is subject to tax at the applicable rate for ordinary income. For these taxpayers, the maximum rate of tax on the net capital gain from a sale or exchange of an asset held for more than 12 months generally is 15%. An exception to the general 15% rule applies, however, to net capital gains attributable to the sale of depreciable real property. Under the exception, gain attributable to prior depreciation deductions not otherwise recaptured as ordinary income under other depreciation recapture rules is subject to a rate of tax of 25%. The Internal Revenue Service has issued final Treasury regulations providing that the 25% rate applies to sales or exchanges of interests in partnerships that hold depreciable real property. Consequently, any gain on the sale or

5

exchange of a unit held for more than 12 months could be treated partly as gain from the sale of depreciable real property subject to the 25% rate, partly as gain from the sale of a long-term capital asset subject to a 15% tax rate, and to the extent that the gain is attributable to unrealized receivables, partly as ordinary income.

     For taxable years beginning after December 31, 2012, the 15% capital gains tax rate is currently scheduled to increase to 20% and the rate applicable to dividends will increase to the tax rate then applicable to ordinary income. In addition, Selling Shareholders that are U.S. domestic corporations may be required to treat up to 20% of some capital gain dividends as ordinary income. Selling Shareholders should consult their own tax advisors regarding the effect, if any, of these changes to tax rates scheduled to occur beginning in 2013.

     Tax Treatment of a Redemption of Units.We have the right to pay to a Selling Shareholder cash in lieu of issuing Common Shares in exchange for Units. If we elect to redeem Units for cash, the tax consequences to a Selling Shareholder would depend on whether or not the redemption is a redemption of all of a Selling Shareholder’s Units. If the redemption is a redemption of all of a Selling Shareholder’s Units, the Selling Shareholder would recognize taxable gain only to the extent that the cash, plus the share of our operating partnership’s liabilities allocable to the redeemed Units, exceeded the Selling Shareholder’s tax basis in all of the Selling Shareholder’s Units immediately before the redemption. On the other hand, the Selling Shareholder would recognize taxable loss only to the extent that the Selling Shareholder’s tax basis in all of the Selling Shareholder’s Units immediately before the redemption exceeded the cash, plus the share of our operating partnership’s liabilities allocable to the redeemed Units. If the redemption is a redemption of less than all of the Selling Shareholder’s Units, the Selling Shareholder would not be permitted to recognize any loss occurring on the transaction and would recognize taxable gain only to the extent that the cash, plus the share of our operating partnership’s liabilities allocable to the redeemed Units, exceeded the Selling Shareholder’s tax basis in all of the Selling Shareholder’s Units immediately before the redemption.

     Basis of Units.In general, a Selling Shareholder who originally received Units in exchange for a contribution of property to our operating partnership had an initial tax basis in the Units equal to the Selling Shareholder’s basis in the contributed property. A Selling Shareholder’s tax basis in the Units generally is increased by the Selling Shareholder’s share of our operating partnership’s taxable income and increases in the Selling Shareholder’s share of liabilities of our operating partnership allocated to such Selling Shareholder. If the Selling Shareholder is an obligated partner under a deficit restoration obligation or has guaranteed partnership indebtedness, the Selling Shareholder’s basis may also include additional liabilities. A Selling Shareholder’s initial tax basis in the Units generally is decreased, but not below zero, by the Selling Shareholder’s share of our operating partnership’s distributions, decreases in the Selling Shareholder’s liabilities in our operating partnership allocated to such Selling Shareholder, the amount of any Selling Shareholder liabilities assumed by the operating partnership, the Selling Shareholder’s share of losses of our operating partnership, and the Selling Shareholder’s share of nondeductible expenditures of our operating partnership that are not chargeable to capital.

     Potential Application of the Disguised Sale Rules to a Redemption of Units.There is a risk that if a Unit is redeemed, particularly if it is redeemed within two years of when it was issued, the IRS might contend that the original transaction pursuant to which the Units were issued should be treated as a “disguised sale” of property. Under the disguised sale rules, unless an exception applies, a partner’s contribution of property to a partnership and a simultaneous or subsequent transfer of money or other consideration, including the assumption of or taking subject to a liability, from the partnership to the partner may be treated as a sale, in whole or in part, of the property by the partner to the partnership. If money or other consideration is transferred by a partnership to a partner within two years of the partner’s contribution of property, the transactions are presumed to be a sale of the contributed property unless the facts and circumstances clearly establish that the transfers do not constitute a sale. If two years have passed between the transfer of money or other consideration and the contribution of property, the transactions will not be presumed to be a sale unless the facts and circumstances clearly establish that the transfers constitute a sale.

     You are advised to consult with your own tax advisors regarding the specific tax consequences of the exchange or redemption of Units, including the federal, state, local, foreign or other tax consequences relating thereto.

PLAN OF DISTRIBUTION

     Any of the Selling Shareholders may from time to time, in one or more transactions, sell all or a portion of the offered Common Shares on the New York Stock Exchange, in the over-the-counter market, on any other national securities exchange on which the Common Shares are listed or traded, in negotiated transactions, in underwritten transactions or otherwise, at prices then prevailing or related to the then current market price or at negotiated prices. The offering price of the

6

offered Common Shares from time to time will be determined by the Selling Shareholders and, at the time of such determination, may be higher or lower than the market price of the Common Shares on the New York Stock Exchange. In connection with an underwritten offering, underwriters or agents may receive compensation in the form of discounts, concessions or commissions from a Selling Shareholder or from purchasers of offered Common Shares for whom they may act as agents, and underwriters may sell offered Common Shares to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agents. Under agreements that may be entered into by us, underwriters, dealers and agents who participate in the distribution of offered Common Shares may be entitled to indemnification by us against certain liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which such underwriters, dealers or agents may be required to make in respect thereof. The offered Common Shares may be sold directly or through broker-dealers acting as principal or agent, or pursuant to a distribution by one or more underwriters on a firm commitment or best-efforts basis. The methods by which the offered Common Shares may be sold include: (a) a block trade in which the broker-dealer so engaged will attempt to sell the offered Common Shares as agent but may position and resell a portion of the block as principal to facilitate the transaction; (b) purchases by a broker-dealer as principal and resale by such broker-dealer for its account pursuant to this prospectus; (c) ordinary brokerage transactions and transactions in which the broker solicits purchasers; (d) an exchange distribution in accordance with the rules of the New York Stock Exchange; (e) privately negotiated transactions; and (f) underwritten transactions. The selling shareholders and any underwriters, dealers or agents participating in the distribution of the offered Common Shares may be deemed to be “underwriters” within the meaning of the Securities Act, and any profit on the sale of the offered Common Shares by the Selling Shareholders and any commissions received by any such broker-dealers may be deemed to be underwriting commissions under the Securities Act.

     When a Selling Shareholder elects to make a particular offer of Common Shares, a prospectus supplement, if required, will be distributed which will identify any underwriters, dealers or agents and any discounts, commissions and other terms constituting compensation from such Selling Shareholder and any other required information will be identified in a prospectus supplement.

     In order to comply with the securities laws of certain states, if applicable, the Common Shares may be sold only through registered or licensed brokers or dealers. In addition, in certain states, the Common Shares may not be sold unless they have been registered or qualified for sale in such state or an exemption from such registration or qualification requirement is available and is complied with.

     We have agreed to pay all costs and expenses incurred in connection with the registration under the Securities Act of the Common Shares registered hereunder, including, without limitation, all registration and filing fees, printing expenses and fees and disbursements of our counsel and accountants. In addition, the Selling Shareholders will pay any brokerage fees and commissions, fees and disbursements of their legal counsel and share transfer and other taxes attributable to the sale of the Common Shares.

Item 15. INDEMNIFICATION OF TRUSTEES AND OFFICERS

     Under Maryland law, a real estate investment trust formed in Maryland is permitted to eliminate, by provision in its Declaration of Trust, the liability of trustees and officers to the trust and its shareholders for money damages except for liability resulting from (a) actual receipt of an improper benefit or profit in money, property or services or (b) acts or omissions established by a final judgment as involving active and deliberate dishonesty and being material to the matter giving rise to the proceeding. The Registrant’s Declaration of Trust includes such a provision eliminating such liability to the maximum extent permitted by Maryland law.

     To the maximum extent permitted by Maryland law in effect from time to time, the Registrant’s bylaws require the Registrant to indemnify and, without requiring a preliminary determination of the ultimate entitlement to indemnification, pay or reimburse, reasonable expenses in advance of final disposition of a proceeding (a) any individual (including the individual’s spouse, children, heirs, estate, executors, or personal or legal representatives for claims arising out of the status of such spouse, children, heirs, estate, executors or personal or legal representatives of such individual (collectively, the “Other Individuals”)) who is a present or former trustee or officer of the Registrant and who is made or threatened to be made a party to the proceeding by reason of his or her service in that capacity or (b) any individual (including Other Individuals) who, while a trustee or officer of the Registrant and at the request of the Registrant, serves or has served as a trustee, officer, partner or trustee of another corporation, real estate investment trust, partnership, joint venture, trust, employee benefit plan or other enterprise and who is made or threatened to be made a party to the proceeding by reason of his or her service in that capacity. The Registrant may, with the approval of its Board of Trustees, provide such indemnification and advance for expenses to an individual (including Other Individuals) who served a predecessor of the Registrant in any of the capacities described in (a) or (b) above and to any employee or agent of the Registrant or a predecessor of the Registrant. The indemnification and payment or reimbursement of expenses shall not be deemed exclusive of or limit in any way other rights to which any person seeking indemnification or payment or reimbursement of expenses may be or may become entitled under any bylaw, regulation, insurance, agreement or otherwise.

     No amendment or repeal of Registrant’s bylaws or Declaration of Trust inconsistent with the foregoing right to indemnification, shall apply to any act or failure to act which occurred prior to such amendment, repeal or adoption. Any indemnification or payment or reimbursement of the expenses permitted by the Registrant’s bylaws shall be furnished in accordance with the procedures provided for indemnification or payment or reimbursement of expenses, as the case may be, under Section 2-418 of the Maryland General Corporation Law (the “MGCL”) for directors of Maryland corporations. The Registrant may provide to trustees and officers such other and further indemnification or payment or reimbursement of expenses, as the case may be, to the fullest extent permitted by the MGCL, as in effect from time to time, for directors of Maryland corporations.

     The Registrant has entered into indemnification agreements with each of its trustees and executive officers. The indemnification agreements require, among other things, that the Registrant indemnify its trustees and executive officers to the fullest extent permitted by law and advance to the trustees and executive officers all related expenses, subject to reimbursement if it is subsequently determined that indemnification is not permitted. Under these agreements, the Registrant must also indemnify and advance all expenses incurred by trustees and executive officers seeking to enforce their rights under the indemnification agreements and may cover trustees and executive officers under the Registrant’s trustees and officers’ liability insurance. Although the form of indemnification agreement offers substantially the same scope of coverage afforded by law, as

II-1

a traditional form of contract it may provide greater assurance to trustees and executive officers that indemnification will be available.

     The partnership agreements of ERP Operating Limited Partnership and its management subsidiaries also provide for indemnification of the Registrant and its officers and trustees to the same extent that indemnification is provided to officers and trustees of the Registrant in its Declaration of Trust, and limit the liability of the Registrant and its officers and trustees to the Operating Partnership and the Management Partnerships and their respective partners to the same extent that the liability of the officers and trustees of the Registrant to the Registrant and its shareholders is limited under the Registrant’s Declaration of Trust.

ITEM 17. Undertakings

The undersigned Registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

     (i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

     (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this registration statement. Notwithstanding the foregoing, any increase or decrease in volume of Securities (if the total dollar value of Securities would not exceed that which was registered) and a deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;

     (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in this registration statement;

Provided, however,That paragraphs (a)(1)(i), (a)(1)(ii),and (a)(1)(iii) of this section do not apply if the registration statement is on Form S-3 or Form F-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in reports field with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus that is filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the Securities offered herein, and the offering of such Securities at that time shall be deemed to be the initialbona fideoffering thereof.

(3) To remove from registration by means of a post-effective amendment any of the Securities being registered which remain unsold at the termination of the offering.

II-2

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

     (i) (A) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and (B) each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(l)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initialbona fideoffering thereof.Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date; or

     (ii) Each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness.Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(5) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the Securities offered herein, and the offering of such Securities at that time shall be deemed to be the initialbona fideoffering thereof.

(6) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to existing provisions or arrangements whereby the registrant may indemnify a trustee, officer or controlling person of the registrant against liabilities arising under the Securities Act, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a trustee, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such trustee, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
