American Sniper is a 2014 American biographical war drama film directed and co-produced by Clint Eastwood and written and executive-produced by Jason Hall, based on the memoir of the same name by Chris Kyle with Scott McEwen and Jim DeFelice. The film follows the life of Kyle, who became the deadliest marksman in U.S. military history with 255 kills from four tours in the Iraq War, 160 of which were officially confirmed by the Department of Defense. While Kyle was celebrated for his military successes, his tours of duty took a heavy toll on his personal and family life. It stars Bradley Cooper as Kyle and Sienna Miller as his wife Taya, with Luke Grimes, Jake McDorman, Cory Hardrict, Kevin Lacz, Navid Negahban, and Keir O'Donnell in supporting roles.

American Sniper premiered at the American Film Institute Festival on November 11, 2014, and had a limited theatrical release in the United States on December 25, 2014, followed by a wide release on January 16, 2015. It received generally positive reviews, with praise for Cooper's lead performance and Eastwood's direction, although it also attracted some controversy over its portrayal of both the Iraq War and Kyle himself. The film grossed over $547 million worldwide, making it the 13th highest-grossing film of 2014, the highest-grossing film with a wide release during the month of January, and Eastwood's highest-grossing film to date.

At the 87th Academy Awards, American Sniper received six nominations, including Best Picture, Best Adapted Screenplay, and Best Actor for Cooper, ultimately winning one for Best Sound Editing.
