The Killers (released in the UK as Ernest Hemingway's "The Killers") is a 1964 American neo noir crime film. Written by Gene L. Coon and directed by Don Siegel, it is the second Hollywood adaptation of Ernest Hemingway's 1927 short story of the same title, following the 1946 version. There is also a 1956 Russian version directed by Andrei Tarkovsky.

The film stars Lee Marvin, John Cassavetes, Angie Dickinson, and Ronald Reagan in his final film role before retiring from acting in 1966 in order to enter politics.

At the time of release, Marvin said that it was his favorite film. The supporting cast features Clu Gulager, Claude Akins, and Norman Fell. In July 2018, it was selected to be screened in the Venice Classics section at the 75th Venice International Film Festival.
