Bloody Mama is a 1970 American exploitation crime film directed by Roger Corman, and starring Shelley Winters in the title role, with Bruce Dern, Don Stroud, Robert Walden, Alex Nicol and Robert De Niro in supporting roles. It was very loosely based on the real story of Ma Barker, who is depicted as a corrupt, mentally-disturbed mother who encourages and organizes the criminality of her four adult sons in Depression-era southern United States.

Corman considered the film one of his favorites in his filmography.
