Marooned is a 1969 American science-fiction film directed by John Sturges and starring Gregory Peck, Richard Crenna, David Janssen, James Franciscus, and Gene Hackman about three astronauts who are trapped and slowly suffocating in space. It was based on the 1964 novel Marooned by Martin Caidin. While the original novel was based on the single-pilot Project Mercury, the film depicted an Apollo command and service module with three astronauts and a space station resembling Skylab. Caidin acted as technical adviser and updated the novel, incorporating appropriate material from the original version.

The film was released less than four months after the Apollo 11 Moon landing, attracting enormous public attention. It won an Academy Award for Best Visual Effects for Robbie Robertson.
