The Witching Hour is a 1921 American silent drama film directed by William Desmond Taylor and written by Julia Crawford Ivers, adapting the 1907 stage play by Augustus E. Thomas. The film stars Elliott Dexter, Winter Hall, Ruth Renick, Robert Cain, A. Edward Sutherland, Mary Alden, and F. A. Turner. The film was released on April 10, 1921, by Paramount Pictures.

This was one of three times that the 1907 stage play was adapted to film (including once in 1916), and according to critic Christopher Workman, was "the least interesting of the three film adaptations". A print of this film currently exists in the Library of Congress.

British-born actor A. Edward Sutherland starred in a number of silent films before moving to the United States where he became a director, working on such Hollywood films as Murders in the Zoo (1932), Beyond Tomorrow (1940) and The Invisible Woman (1940).
