Legion of Terror is a 1936 American drama/action film, directed by Charles C. Coleman. The film, which stars Bruce Cabot, Marguerite Churchill, Ward Bond, and Crawford Weaver, is a fictionalized story about the real-life Ku Klux Klan splinter group called the Black Legion of the 1930s. It was inspired by the May 1935 murder in Michigan of Charles Poole, a Works Progress Administration worker.

The film preceded and also inspired the making of the critically acclaimed 1937 Warner Bros. feature film Black Legion, which co-starred Humphrey Bogart, Dick Foran, Erin O'Brien-Moore and Ann Sheridan and which was based on the same case.
