"Halloween of Horror" is the fourth episode of the twenty-seventh season of the animated television series The Simpsons, and the 578th episode of the series overall. It originally aired in the United States on Fox on October 18, 2015.

It is the first Halloween-themed episode of The Simpsons to be fully canon and not a part of the Treehouse of Horror series. The episode received highly positive reviews from critics.

The day before Halloween, the Simpson family completely decorates their house, calling it "Everscream Terrors". Homer stored the plastic skeletons too close to the furnace, and he decides to take the remains to Grampa's home and buy something new at the Halloween pop-up store. On their way to the store, Lisa and Bart see a sign advertising the upcoming Krustyland Halloween Horror Night, and share their excitement for it. At the Halloween shop, Apu gets angry at three lazy employees who are sleeping on their jobs, telling them to go back to work. While Homer is looking for a decoration to replace the skeletons, one of the workers gives Homer a deal where if he buys one "Señor Skeleton", he will give Homer a set of four of them for free. Homer accepts the deal and tells Apu about it, who promptly fires the workers. The three then promise revenge on Homer.

Later, Homer takes the children to the Halloween Horror Night. Although the Horror Night is not real, Lisa gets scared at the zombies and the park is closed. At school, Lisa's trauma makes her scared from even the simplest Halloween figures such as paper zombies and bats. She then hides inside a locker only to be rescued later by Marge. Back home, Marge realizes Lisa's problem and tells Homer they should shut down Everscream Terrors making both Homer and Bart upset. In order to reconcile with Bart, Marge takes him and Maggie to the most famous Halloween block party at a cul-de-sac in Springfield, leaving Lisa and Homer alone. Homer tries to bond with Lisa offering to do a puzzle with her. At the same time, the three workers that Homer inadvertently got fired have come for their revenge, and begin to stalk Homer and Lisa.
