Friendly Persuasion is a 1956 American Civil War drama film produced and directed by William Wyler. It stars Gary Cooper, Dorothy McGuire, Anthony Perkins, Richard Eyer, Robert Middleton, Phyllis Love, Mark Richman, Walter Catlett and Marjorie Main. The screenplay by Michael Wilson was adapted from the 1945 novel The Friendly Persuasion by Jessamyn West. The movie tells the story of a Quaker family in southern Indiana during the American Civil War and the way the war tests their pacifist beliefs.

The film received positive reviews, praised for its performances, but faced some criticism for inaccuracies in portraying Quaker views. It earned $4 million at the box office, won the Palme d'Or at the Cannes Film Festival and received six Academy Award nominations including Best Picture. Michael Wilson, the screenwriter, was initially uncredited due to being on the Hollywood blacklist but was later restored in 1996.

Ronald Reagan gifted the film to Soviet leader Mikhail Gorbachev, symbolizing the pursuit of peaceful solutions to conflicts.
