Blitz Wolf is a 1942 American animated propaganda short film produced and distributed by Metro-Goldwyn-Mayer. A parody of the Three Little Pigs told via a World War II perspective, the short was directed by Tex Avery (in his first cartoon for MGM) and produced by Fred Quimby. It was nominated for the Academy Award for Best Short Subject: Cartoons but lost to Der Fuehrer's Face, another anti-Nazi World War II parody featuring Donald Duck.
