Man on the Moon is a 1999 biographical comedy-drama film about the late American entertainer Andy Kaufman, starring Jim Carrey as Kaufman. The film was directed by Miloš Forman and also features Danny DeVito, Courtney Love, and Paul Giamatti.

The story traces Kaufman's steps from childhood through the comedy clubs and television appearances that made him famous, including his memorable appearances on Saturday Night Live, Late Night with David Letterman, Fridays, and his role as Latka Gravas on the sitcom Taxi, which was popular among viewers but disruptive for Kaufman's co-stars. The film pays particular attention to the various inside jokes, scams, put-ons, and happenings for which Kaufman was famous, most significantly his long-running "feud" with wrestler Jerry "The King" Lawler and his portrayal of the character of bawdy lounge singer Tony Clifton.

It was released on December 22, 1999, in the United States and May 5, 2000, in the United Kingdom by Universal Pictures and Warner Bros. Pictures in some markets. Although the film was unsuccessful commercially and received mixed reviews, Carrey received critical acclaim for his performance and won a Golden Globe, his second in a row after his award for The Truman Show. His win was in the Musical or Comedy category.

The documentary Jim & Andy: The Great Beyond was released in 2017 and chronicles Carrey's performance as Kaufman in the film, a performance he maintained during much of the film's production.
