The Lords of Flatbush is a 1974 American drama film about a street gang in leather jackets from the Flatbush neighborhood of Brooklyn, New York. Directed by Martin Davidson and Stephen Verona, The Lords of Flatbush starred Perry King, Henry Winkler and Sylvester Stallone (who also wrote additional dialogue).

A portion of this film was shot in Stamford, Connecticut. The wedding scenes were filmed in an area of town called Cove on Dale Street. Exterior scenes were shot at Samuel J. Tilden High School in the East Flatbush section of Brooklyn.

Set in 1958, the coming-of-age story follows four Brooklyn teenagers known as The Lords of Flatbush. The Lords chase girls, steal cars, play pool and hang out at a local malt shop. The film focuses on Chico (Perry King) attempting to win over Jane (Susan Blakely), a girl who wants little to do with him, and Stanley (Sylvester Stallone), who impregnates his girlfriend, Frannie (Maria Smith), who wants him to marry her.
