The Fighting Sullivans, originally released as The Sullivans, is a 1944 American biographical war film directed by Lloyd Bacon and written by Edward Doherty, Mary C. McCall Jr., and Jules Schermer. It was nominated for a now-discontinued Academy Award for Best Story.

The story retells, with some poetic license, the lives of five Irish-American Sullivan brothers, who grew up in Iowa during the days of the Great Depression and served together in the United States Navy during World War II.
