This Is Halloween is the opening number from The Nightmare Before Christmas, the 1993 stop-motion film directed by Henry Selick and produced by Tim Burton, with music by Danny Elfman. Sung by the residents of Halloween Town as they introduce themselves, it quickly became the film's signature song and a seasonal anthem far beyond the movie itself. Each October it resurfaces in costume videos, party playlists, haunted attractions and social media edits, because its instantly recognisable chorus works as shorthand for Halloween itself.
