House II: The Second Story is a 1987 American comedy horror film written and directed by Ethan Wiley from an original story by Fred Dekker. It serves as the second installment in the House film series, and is a standalone sequel to the first movie. While the plots and characters are unrelated, House II involves a storyline centered around a new mansion with a supernatural connection. The tone is highlighted with a greater focus on comedy, with a tone even lighter than the original.

House II: The Second Story was released on August 28, 1987, grossing $10 million worldwide against a $3 million budget and received negative reviews from critics.

In the film, a duo of Yuppies settle in an old family mansion, and learn of the existence of a crystal skull owned by a recent ancestor of one of them. They decide to unbury the ancestor, in order to see if the skull was among his grave goods. Instead, they accidentally revive the ancestor in the form of a zombie. The mansion contains time portals into other historical eras, and the characters time travel to the Jurassic, to the Aztec Empire, and to the American Old West. They bring back animals and people from the past, but eventually decide to permanently settle in the Old West.
