All Souls' Eve is a 1921 American silent drama film directed by Chester M. Franklin and starring Mary Miles Minter. The film is based on the mystical 1920 Broadway play of the same name by Anne Crawford Flexner, with a story by Elmer Blaney Harris. Much was made of the film's use of double, triple and quadruple exposures to enable Minter to play two parts within the same scenes.

Mary Miles Minter was an American actress, and one of the leading ladies who established the early Hollywood star system. She appeared in 53 silent films from 1912 to 1923.
