The Martian is a 2015 science fiction film directed by Ridley Scott and starring Matt Damon. Drew Goddard adapted the screenplay from the 2011 novel by Andy Weir. It also stars Jessica Chastain, Jeff Daniels, Kristen Wiig, Chiwetel Ejiofor, Sean Bean, Michael Peña, Kate Mara, Sebastian Stan, Aksel Hennie, Mackenzie Davis, Donald Glover, and Benedict Wong. The film depicts an astronaut's struggle to survive on Mars after being left behind and NASA's efforts to return him to Earth.

The Martian was produced through 20th Century Fox in the United Kingdom and the United States. Producer Simon Kinberg began developing the film after Fox optioned the novel in March 2013. Goddard, who adapted the novel into a screenplay, was initially attached to direct, but production was only approved after Scott replaced Goddard as director and Damon was cast as the main character. Filming began in November 2014 and lasted about 70 days. Twenty sets were built on one of the largest sound stages in the world in Budapest, Hungary. Wadi Rum in Jordan was also used for exterior filming.

The film premiered at the 2015 Toronto International Film Festival on September 11, 2015. It was released in the UK on September 30, 2015, and in the US on October 2, 2015, in 2D, 3D, IMAX 3D and 4DX. It received positive reviews and numerous accolades, including seven nominations at the 88th Academy Awards. Grossing over $630 million worldwide, The Martian became Scott's highest-grossing film to date and the tenth-highest-grossing film of 2015.
