Trick or Tweet is a 1959 Warner Bros. Merrie Melodies animated cartoon directed by Friz Freleng. The short was released on March 21, 1959, and stars Tweety and Sylvester.

Tweety and Sylvester are voiced by Mel Blanc, and Sam, the orange-red cat acting as Sylvester's rival, is performed by an uncredited Daws Butler, doing a voice reminiscent of Frank Fontaine's "John" from The Jack Benny Program and "Crazy Guggenheim" from The Jackie Gleason Show.

The title is a play on the phrase "Trick or treat".
