Black Legion is a 1937 American crime drama film, directed by Archie Mayo, with a script by Abem Finkel and William Wister Haines based on an original story by producer Robert Lord. The film stars Humphrey Bogart, Dick Foran, Erin O'Brien-Moore and Ann Sheridan. It is a fictionalized treatment of the historic Black Legion of the 1930s in Michigan, a white vigilante group. A third of its members lived in Detroit, which had also been a center of the Ku Klux Klan in the 1920s.

Humphrey DeForest Bogart, colloquially nicknamed Bogie, was an American actor. His performances in classic Hollywood cinema films made him an American cultural icon. In 1999, the American Film Institute selected Bogart as the greatest male star of classic American cinema.
