Gideon's Day (U.S. title: Gideon of Scotland Yard) is a 1958 police procedural crime film directed by John Ford and starring Jack Hawkins, Dianne Foster and Cyril Cusack. The screenplay was by T.E.B. Clarke, adapted from John Creasey's 1955 novel of the same title.

This was the first film to feature a character named George Gideon, but Jack Hawkins had played a similar role in the British film The Long Arm (1956) two years earlier. Gideon was later played by John Gregson in the TV series Gideon's Way.
