The Americanization of Emily is a 1964 American black-and-white black comedy anti-war film directed by Arthur Hiller, written by Paddy Chayefsky, and starring James Garner, Julie Andrews, Melvyn Douglas, James Coburn, Joyce Grenfell, and Keenan Wynn. Set during World War II, the film follows a United States Navy adjutant who is roped into a reckless interservice rivalry-fueled stunt by his superiors, becoming a war hero by being the first American sailor killed on D-Day.

Chayefsky's screenplay loosely was adapted from the 1959 novel of the same name by William Bradford Huie, who had been a Seabee officer during Operation Overlord. Controversial for its stance during the dawn of the Vietnam War, the film has since been praised as a "vanguard anti-war film". Both James Garner and Julie Andrews have considered the film to be the favorite of their films.
