The Lone Wolf Spy Hunt is a 1939 American adventure film directed by Peter Godfrey and written by Jonathan Latimer. The film stars Warren William and Ida Lupino and was released by Columbia Pictures, on January 27, 1939.

The Lone Wolf character dates back to 1914, when author Louis Joseph Vance invented him for a series of books, later adapted to twenty-four Lone Wolf films (1917–1949). Warren Williams starred in nine of these films (1939–1943), with The Lone Wolf Spy Hunt being the first starring William as Michael Lanyard. His next film was The Lone Wolf Strikes, in 1940.
