Sh! The Octopus is a 1937 American comedy mystery film produced by Warner Bros., directed by William McGann, and starring Hugh Herbert, Allen Jenkins and Marcia Ralston. While contract players Herbert and Jenkins frequently appeared in the same picture, this is the only film to present them as an actual team.

In 2022, the film garnered attention on social media for a character transformation scene that was accomplished using practical effects with a combination of makeup and graduated filters.
