Item 4.01 Changes in Registrant’s Certifying Accountant.

     (a) Previous independent registered public accounting firm.

          On June 1, 2010, the Audit Committee of the Board of Directors of Forrester Research, Inc. (the “Company”) approved the dismissal of BDO Seidman, LLP (“BDO”) as the Company’s independent registered public accounting firm.

          The reports of BDO on the Company’s financial statements for the fiscal years ended December 31, 2009 and 2008 did not contain an adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles.

          During the Company’s fiscal years ended December 31, 2009 and 2008, and through June 1, 2010, there have been no disagreements with BDO on any matter of accounting principles or practices, financial statement disclosure, or auditing scope and procedure, which disagreements, if not resolved to the satisfaction of BDO, would have caused BDO to make reference thereto in its reports on the financial statements.

          During the Company’s fiscal years ended December 31, 2009 and 2008, and through June 1, 2010, there have been no reportable events as defined in Item 304(a)(1)(v) of Regulation S-K.

          The Company has requested that BDO furnish the Company with a letter addressed to the U.S. Securities and Exchange Commission stating whether BDO agrees with the disclosure contained in this report. A copy of such letter is filed as Exhibit 16.1 to this Form 8-K.

     (b) New independent registered public accounting firm

          On June 1, 2010, the Audit Committee of the Board of Directors of the Company engaged PricewaterhouseCoopers LLP (“PwC”) as its independent registered public accounting firm for the fiscal year ending December 31, 2010. During the years ended December 31, 2009 and 2008, and through June 1, 2010, the Company did not consult with PwC with respect to any of the matters described in Item 304(a)(2)(i) and (ii) of Regulation S-K.
