Machine-Gun Kelly is a 1958 film noir directed by Roger Corman that chronicles the criminal activities of the real-life gangster George "Machine Gun" Kelly. Despite its small budget, the film received positive critical reviews.

Charles Bronson's lead role in Machine-Gun Kelly was his first in a feature film. Corman called the film "a major turning point in my career," because it was the first for which he had received serious critical attention.
