Psycho is a 1998 American psychological horror film produced and directed by Gus Van Sant, and starring Vince Vaughn, Julianne Moore, Viggo Mortensen, William H. Macy, and Anne Heche. It is a modern remake of Alfred Hitchcock's 1960 film of the same name, in which an embezzler arrives at an old motel run by a mysterious man named Norman Bates; both films are adapted from Robert Bloch's 1959 novel.

Though filmed in color and set in 1998, the film is closer to a shot-for-shot retelling than most remakes, often copying Hitchcock's camera movements and editing, including the original script by Joseph Stefano (and uncredited writer Alma Reville) mostly being carried over. Bernard Herrmann's musical score is reused as well, though with a new arrangement by Danny Elfman and Steve Bartek, recorded in stereo. Some changes are introduced to account for advances in technology since the original film and to make the content more explicit. The film's murder sequences are also intercut with surreal images.

Psycho was a commercial failure and received polarized reviews from critics who criticized the similarities to the original film. It won the Golden Raspberry Awards for Worst Remake and Worst Director, and was nominated for Worst Actress (Heche). However, it earned two Saturn Award nominations for Best Actress (Heche) and Best Writing (Stefano).
