Wyatt Earp is a 1994 American epic biographical Western drama film directed and produced by Lawrence Kasdan, and co-written by Kasdan and Dan Gordon. The film covers the lawman of the same name's life, from an Iowa farmboy, to a feared marshal, to the feud in Tombstone, Arizona that led to the O.K. Corral gunfight. Starring Kevin Costner in the title role, it features an ensemble supporting cast that includes Gene Hackman, Mark Harmon, Michael Madsen, Bill Pullman, Dennis Quaid, Isabella Rossellini, Tom Sizemore, JoBeth Williams, Mare Winningham and Jim Caviezel in one of his earliest roles.

The film was released a mere six months after Tombstone, also about Earp and the O.K. Corral gunfight. Unlike Tombstone, it was a box office failure and received mixed to negative reviews, with criticism for its three-hour runtime, although its production values were praised.
