Invisible Avenger is a 1958 American film noir crime film directed by James Wong Howe, Ben Parker and John Sledge. The film was a compilation of two television pilot episodes of a 1957 Republic Pictures TV show called The Shadow. When the show failed to sell, the episodes (one of which was directed by cinematographer James Wong Howe) were edited together and released as a theatrical feature called Invisible Avenger.

The film was re-released in 1962 under the title Bourbon Street Shadows by the Louisiana-based MPA films. The episodes were shot on location in New Orleans.
