Deborah Platt Majoras is the former chairman of the Federal Trade Commission, appointed May 11, 2004, by President George W. Bush and sworn in on August 16, 2004. President Bush had announced his intention to appoint her to the position on July 30, 2004. In early 2008, she announced that she was leaving the FTC to become vice president and general counsel for Procter & Gamble, the largest consumer products company in the United States.

Majoras filled the FTC vacancy created by Timothy Muris, who announced May 11, 2004 that he would step down to become a law professor at George Mason University. Majoras was replaced by William Kovacic in March 2008.

While she did not have formal powers to block investigations into Intel over antitrust issues, she is credited with stopping such, until June 2008.
