Rhapsody Rabbit is a 1946 American animated comedy short film in the Merrie Melodies series, directed by Friz Freleng and featuring Bugs Bunny. The movie was originally released to theaters by Warner Bros. Pictures on November 9, 1946. This short is a follow-up of sorts to Freleng's 1941 Academy Award-nominated Rhapsody in Rivets, which featured the "Hungarian Rhapsody No. 2" by Franz Liszt. The "instrument" used to perform the "Hungarian Rhapsody" in Rhapsody in Rivets is a skyscraper under construction, while this short features Bugs playing the piece at a piano while being pestered by a mouse.

In 1946, film critic James Agee wrote in The Nation that the short is "the funniest thing I have seen since the decline of sociological dancing," saying, "The best of it goes two ways: one, very observant parody of concert-pianistic affectations, elegantly thought out and synchronized; the other, brutality keyed into the spirit of the music to reach greater subtlety than I have ever seen brutality reach before."

Rhapsody Rabbit was the first cartoon to be broadcast on Cartoon Network when the channel launched on October 1, 1992.
