Daffy Duck and the Dinosaur is a 1939 Warner Bros. Merrie Melodies animated cartoon short directed by Chuck Jones. The cartoon was released on April 22, 1939, and is the first Daffy Duck cartoon directed by Jones.

Daffy Duck and the Dinosaur is set in a chronologically twisted Stone Age and features Daffy Duck going up against a caveman named Casper (who is a caricature of Jack Benny) and his pet Brontosaurus Fido.

This is the last cartoon with the Vitaphone intro, which was first used in The Phantom Ship in 1936.
