The Long Goodbye is a 1973 American satirical neo-noir film directed by Robert Altman, adapted by Leigh Brackett from Raymond Chandler's 1953 novel of the same name. The film stars Elliott Gould as Philip Marlowe and features Sterling Hayden, Nina Van Pallandt, Jim Bouton, Mark Rydell, and an early, uncredited appearance by Arnold Schwarzenegger.

The story's setting was moved from the 1940s to 1970s Hollywood. The film has been called "a study of a moral and decent man cast adrift in a selfish, self-obsessed society where lives can be thrown away without a backward glance ... and any notions of friendship and loyalty are meaningless."

United Artists released the film on March 7, 1973. It received mixed to positive reviews upon release, but its critical assessment has grown over time. In 2021, the Library of Congress selected the film for preservation in the United States National Film Registry as "culturally, historically, or aesthetically significant".
