The Shadow is a fictional character created by American magazine publishers Street & Smith and writer Walter B. Gibson. Originally created to be a mysterious radio show narrator, and developed into a distinct literary character in 1931 by Gibson, The Shadow has been adapted into other forms of media, including American comic books, comic strips, serials, video games, and at least five feature films. The radio drama included episodes voiced by Orson Welles.

Street & Smith entered into a new broadcasting agreement with Blue Coal in 1937, and that summer Gibson teamed with scriptwriter Edward Hale Bierstadt to develop the new series. The Shadow returned to network airwaves with the episode "The Death House Rescue" on September 26, 1937, over the Mutual Broadcasting System. Thus began the "official" radio drama, with 22-year-old Orson Welles starring as Lamont Cranston, a "wealthy young man about town." Once The Shadow joined Mutual as a half-hour series on Sunday evenings, the program was broadcast by Mutual until December 26, 1954.
