Transylvania 6-5000 (1963) is a Warner Bros. Merrie Melodies animated short directed by Chuck Jones. The short was released on November 30, 1963, and stars Bugs Bunny. It was the last original Bugs Bunny short Jones made for Warner Bros. Cartoons before Jones left for Metro-Goldwyn-Mayer to found his own studio, Sib Tower 12 Productions. It was his second-to-last cartoon at Warner Bros. before moving to MGM, and the second-to-last Warner cartoon in 1963.

Bugs demonstrates how to handle a pesky vampire with six simple magic incantations. The title is a pun on "Pennsylvania 6-5000", a song associated with Glenn Miller and referring to the now-archaic system of telephone exchange names where the first two characters of a telephone number were expressed as letters: "Transylvania 6-5000" stands for "TR 6-5000" which devolves to 876-5000.
