Wabbit Twouble ("Rabbit Trouble") is a Merrie Melodies cartoon starring Bugs Bunny, produced by Leon Schlesinger Productions and released on December 20, 1941 by Warner Bros. Pictures. This is the first of several Bugs Bunny cartoon titles that refer to Elmer Fudd's speech impediment, with the names of Bob Clampett, Sidney Sutherland, and Carl Stalling, as well as the roles of Story, Supervision, and Musical Direction, intentionally misspelled in the credits to match the speech impediment.

In the cartoon, Elmer expects to find rest and relaxation at Jellostone National Park. He mistakenly sets up camp in the neighborhood of Bugs' rabbit hole, but Bugs (and a neighboring bear) do not have much leisure in mind.

Tex Avery began the project which Clampett finished; Avery is not credited on screen. This was the first Bugs Bunny and Elmer Fudd cartoon directed by Clampett, with a story by Dave Monahan and musical direction by Carl W. Stalling. Although Sid Sutherland is the only credited animator, the short was also animated by Virgil Ross, Rod Scribner, and Robert McKimson. Mel Blanc provided the voices for Bugs and the bear, and Arthur Q. Bryan provided the voice for Elmer.
