Batman: The Long Halloween is a 13-issue American comic book limited series written by Jeph Loeb with art by Tim Sale. It was originally published by DC Comics in 1996 and 1997. It was the follow-up to three Batman: Legends of the Dark Knight Halloween Specials by the same creative team. The series' success led to Loeb and Sale to reteam for two sequels, Batman: Dark Victory and Catwoman: When in Rome, which are set concurrently.
