Murder by Contract is a 1958 American film noir crime film directed by Irving Lerner. Academy Award-nominated screenwriter Ben Maddow did uncredited work on the film. Centering on an existentialist hit man assigned to kill a woman, the film is often praised for its spare style and peculiar sense of cool.

The film has exerted an influence on American cinema, most notably on director Martin Scorsese, who famously cited Murder by Contract as "the film that has influenced [him] most."
