Who Killed Cock Robin is a Silly Symphonies animated short film released on June 26, 1935, by United Artists, produced by Walt Disney and directed by David Hand. It is based on the nursery rhyme Who Killed Cock Robin?. It was nominated for the Best Short Subject (Cartoons) Oscar but lost to Disney's own Three Orphan Kittens.
An extract from the cartoon was featured the following year in Alfred Hitchcock's Sabotage; the film's opening credits thank Disney for giving permission.
