The Big Red One is a 1980 American epic war film written and directed by Samuel Fuller, and starring Lee Marvin alongside an ensemble supporting cast, including Mark Hamill, Robert Carradine, Siegfried Rauch, Bobby Di Cicco, and Kelly Ward.

Based on Fuller's own experiences as a soldier in World War II, it was produced independently on a low budget, and shot on location in Israel as a cost-saving measure. It was heavily cut on its original release, but a restored version, The Big Red One: The Reconstruction, premièred at the 2004 Cannes Film Festival, seven years after Fuller's death. Fuller wrote a book with the same title, which was more a companion novel than a novelization of the film, although it features many of the scenes that were originally cut.
