Wyatt Earp is a 1994 American epic biographical Western drama film about the the lawman of the same name. Directed by Lawrence Kasdan, who co-wrote the screenplay with Dan Gordon, the film follows Earp from his early life to his career as a marshal and his involvement in the O.K. Corral gunfight. It features an ensemble cast led by Kevin Costner as Earp, with Gene Hackman, Mark Harmon, Michael Madsen, Bill Pullman, Dennis Quaid, Isabella Rossellini, Tom Sizemore, JoBeth Williams, and Mare Winningham in supporting roles.

The film was developed in competition with Tombstone, another adaptation of Earp's life and the O.K. Corral gunfight. Released on June 24, 1994, Wyatt Earp received mixed reviews from critics, who praised the performances and Kasdan's direction, but criticized the three-hour runtime and unfavorably compared it to Tombstone, which was released six months earlier. It was also a box office failure, grossing $55.9 million on a $63 million budget.
