Unforgiven is a 1992 American Revisionist Western film directed, produced by, and starring Clint Eastwood in the lead role and written by David Webb Peoples. The film tells the story of William Munny, an aging outlaw and killer who takes on one more job, years after he had turned to farming. The film co-stars Gene Hackman, Morgan Freeman, and Richard Harris.

Unforgiven grossed over $159 million on a budget of $14.4 million and received widespread critical acclaim, with praise for the acting (particularly from Eastwood and Hackman), directing, editing, themes and cinematography. The film won four Academy Awards: Best Picture and Best Director for Clint Eastwood, Best Supporting Actor for Gene Hackman, and Best Film Editing for editor Joel Cox. Eastwood was nominated for the Academy Award for Best Actor for his performance, but he lost to Al Pacino for Scent of a Woman. The film was the third Western to win Best Picture, following Cimarron (1931) and Dances with Wolves (1990). Eastwood dedicated the film to directors and mentors Sergio Leone and Don Siegel.

In 2004, Unforgiven was selected for preservation in the United States National Film Registry by the Library of Congress as being deemed "culturally, historically, or aesthetically significant". The film was remade into a 2013 Japanese film, also titled Unforgiven, which stars Ken Watanabe and changes the setting to the early Meiji era in Japan. Eastwood has long asserted that the film would be his last Western, concerned any future projects would simply rehash previous plotlines or imitate someone else's work.
