Strange Stories was a pulp magazine which ran for thirteen issues from 1939 to 1941. It was edited by Mort Weisinger, who was not credited. Contributors included Robert Bloch, Eric Frank Russell, C. L. Moore, August Derleth, and Henry Kuttner. Strange Stories was a competitor to the established leader in weird fiction, Weird Tales. With the launch, also in 1939, of the well-received Unknown, Strange Stories was unable to compete. It ceased publication in 1941 when Weisinger left to edit Superman comic books.
