The House by the Cemetery (Italian: Quella villa accanto al cimitero) is a 1981 Italian supernatural slasher film directed by Lucio Fulci, co-written with Dardano Sacchetti and Giorgio Mariuzzo, and starring Catriona MacColl, Paolo Malco, Ania Pieroni, Giovanni Frezza, Silvia Collatina, and Dagmar Lassander. The third and final installment in Fulci's Gates of Hell trilogy, preceded by City of the Living Dead and The Beyond, the plot revolves around a series of murders committed by a ghoulish and demonic serial killer taking place in a Massachusetts home that happens to be hiding a gruesome secret within its basement walls.

Fulci developed the screenplay for The House by the Cemetery with inspiration from the works of H. P. Lovecraft, while co-writer Sacchetti was influenced by the novella The Turn of the Screw by Henry James. Principal photography took place in the spring of 1980 in New York City and the Greater Boston area, with additional photography occurring in Rome at the De Paolis In.Co.R. Studios.

Upon its premiere in Italy in August 1981, The House by the Cemetery became a domestic box-office success, grossing £1.408 billion, making it Fulci's most profitable horror film released in the 1980s.
