"1984" is an American television commercial which introduced the Apple Macintosh personal computer for the first time. It was conceived by Steve Hayden, Brent Thomas and Lee Clow at Chiat/Day, Venice, produced by New York production company Fairbanks Films, and directed by Ridley Scott. Anya Major performed as the unnamed heroine and David Graham as Big Brother. Its only U.S. daytime televised broadcast was on January 22, 1984 during and as part of the telecast of the third quarter of Super Bowl XVIII. Chiat/Day also ran the ad one other time on television, in December 1983 right before the 1:00 am sign-off on KMVT in Twin Falls, Idaho, so that the advertisement could be submitted to award ceremonies for that year.

In addition, starting on January 17, 1984 it was screened prior to previews in movie theaters for a few weeks. It has since been seen on television commercial compilation specials, as well as in "Retro-mercials" on TV Land. The estate of George Orwell and the television rightsholder to the novel 1984 considered the commercial to be a flagrant copyright infringement, and sent a cease-and-desist letter to Apple and Chiat/Day in April 1984. The commercial was never televised as a commercial after that.
