Barbara Feldon is an American actress primarily known for her roles on television. Her most prominent role was that of Agent 99 in the 1965–1970 sitcom Get Smart.

Get Smart is an American comedy television series parodying the secret agent genre that had become widely popular in the first half of the 1960s with the release of the James Bond films. It was created by Mel Brooks and Buck Henry, and had its television premiere on NBC on September 18, 1965. It stars Don Adams as agent Maxwell Smart, Barbara Feldon as Agent 99, and Edward Platt as The Chief. Henry said that they created the show at the request of Daniel Melnick to capitalize on James Bond and Inspector Clouseau, "the two biggest things in the entertainment world today". Brooks described it as "an insane combination of James Bond and Mel Brooks comedy".
