Three Brave Men is a 1956 American drama film directed by Philip Dunne and starring Ray Milland, Ernest Borgnine and Frank Lovejoy.

The film was based on real-life events arising in Greenbelt, Maryland, the investigation of Abraham Chasanow, a U.S. government employee, as a security risk in 1954-55. Bosley Crowther in The New York Times called the film a "plainly pussyfooting picture" in which "the obvious point of the real-life drama is avoided and an imaginary target is devised." The film assigned blame to a vague personal enemy and local gossips while the role of those responsible for the investigation, in his view, was "sweetly glossed". Chasanow's name in the film is Bernie Goldsmith. Chasanow served as an adviser on the film.
