Exhibit 23.01

CONSENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders

Macromedia, Inc.:

We consent to the incorporation by reference in the registration statements (Nos. 333-98495, 333-67960, 333-77040, 333-57708, 333-44016, 333-92233, 333-89247, 333-64141, 333-39285, 333-24713 and 333-08435) on Form S-8 of Macromedia, Inc. and subsidiaries of our reports dated June 14, 2005, with respect to the consolidated balance sheets of Macromedia, Inc. and subsidiaries as of March 31, 2005 and 2004, and the related consolidated statements of income, changes in stockholders’ equity and comprehensive income and cash flows for each of the years in the three-year period ended March 31, 2005, and the related financial statement schedule, management’s assessment of the effectiveness of internal control over financial reporting as of March 31, 2005, and the effectiveness of internal control over financial reporting as of March 31, 2005, which reports appear in the March 31, 2005, annual report on Form 10-K of Macromedia, Inc.

Our report dated June 14, 2005, on management’s assessment of the effectiveness of internal control over financial reporting and the effectiveness of internal control over financial reporting as of March 31, 2005, expresses our opinion that Macromedia, Inc. did not maintain effective internal control over financial reporting as of March 31, 2005 because of the effect of a material weakness on the achievement of the objectives of the control criteria and contains an explanatory paragraph that states that the Company’s policies and procedures did not include adequate management oversight and review of the Company’s accounting for income taxes. This lack of adequate management oversight and review resulted in errors in the Company’s income tax expense and the corresponding deferred tax assets and liabilities. Because of this deficiency, there is more than a remote likelihood that a material misstatement in the Company’s annual or interim consolidated financial statements would not be prevented or detected.
