Phantom of the Megaplex is a 2000 American comedy mystery film and Disney Channel original movie, produced by the Disney Channel. With a title and concept very loosely based on Gaston Leroux's 1910 novel The Phantom of the Opera, the film concerns strange happenings at a monstrous megaplex on the night of the premiere of a major movie, Midnight Mayhem.

The central character, played by Taylor Handley, is Pete Riley, the 17-year-old assistant manager of the theater. He has to cope with malfunctioning equipment, disappearing staff, and a broken popcorn machine, among other headaches. He investigates to see if the troubles are coincidence or the result of sabotage by a mysterious "phantom". The senior manager of the theater is played by Rich Hutchman, and Ricky Mabe, Julia Chantrey, Joanne Boland, J.J. Stocker, and Lisa Ng appear as other employees of the theater. Caitlin Wachs and Jacob Smith play the central character's younger siblings, and Heather and Jennifer Bertram appear as his love interest and her friend.
