Rain Man is a 1988 American road comedy-drama film directed by Barry Levinson and written by Barry Morrow and Ronald Bass. It tells the story of abrasive and selfish wheeler-dealer Charlie Babbitt (Tom Cruise), who discovers that his estranged father has died and bequeathed his multimillion-dollar estate to his other son, Raymond (Dustin Hoffman), an autistic savant whose existence Charlie was unaware of. Morrow created the character of Raymond after meeting real-life savant Kim Peek; his characterization was based on both Peek and Bill Sackter, a good friend of Morrow who was the subject of Bill, an earlier film that Morrow wrote.

Rain Man competed at the 39th Berlin International Film Festival, where it won the highest prize: the Golden Bear. The film was released theatrically by MGM/UA Communications Co. under the United Artists label in the United States on December 16, 1988, to critical and commercial success. Praise was given to Levinson's direction, the performances (particularly Cruise and Hoffman), the screenplay, the musical score, the cinematography, and the film's portrayal of autism. The film grossed $354 million on a $25 million budget, becoming the highest-grossing film of 1988, and received a leading eight nominations at the 61st Academy Awards, winning four (more than any other film nominated): Best Picture, Best Director, Best Actor (for Hoffman), and Best Original Screenplay.

As of 2024, Rain Man is the only film to win both the Berlin International Film Festival's highest award and the Academy Award for Best Picture in the same year. It was also the last film released by Metro-Goldwyn-Mayer (MGM) to be nominated for Best Picture until Licorice Pizza in 2021 — 33 years later.
