The Longest Yard is a 1974 American prison sports comedy-drama film directed by Robert Aldrich, written by Tracy Keenan Wynn, based on a story by producer Albert S. Ruddy, and starring Burt Reynolds, Eddie Albert, Ed Lauter, Michael Conrad and James Hampton. The film was released as The Mean Machine in the United Kingdom and South Africa. The film follows a former NFL player recruiting a group of prisoners and playing football against their guards. It features many real-life football players, including Ray Nitschke of the Green Bay Packers.

The film has been remade three times: as the 2001 British film Mean Machine (a shortened version of the title used for the original's UK release), starring Vinnie Jones, the 2005 film remake, The Longest Yard featuring Adam Sandler and Reynolds as coach Nate Scarborough, and as the 2015 Egyptian film Captain Masr. In the two international remakes from 2001 and 2015, the sport was changed from gridiron football to association football.
