Captain Lightfoot is a 1955 American CinemaScope Technicolor adventure film directed by Douglas Sirk starring Rock Hudson, Barbara Rush and Jeff Morrow and is Sirk's adaptation of a book by W. R. Burnett written in 1954.

The movie is set in the early 19th century with the hero and his brother-in-arms becoming highwaymen, robbing the wealthy around the foothills of Dublin, Ireland. Captain Lightfoot falls in love, and the ensuing drama threatens everyone's safety.

The movie was filmed around Clogherhead, County Louth, Marlay Park in Rathfarnham, County Dublin, and in the Powerscourt Estate in Enniskerry, County Wicklow. Slane Castle in Slane County Meath was used as the exterior of Ballymore Castle.

Director/writer Michael Cimino utilized the nicknames of Martin and Doherty for the main characters in his debut feature film, Thunderbolt and Lightfoot (1974).
