Remakes of films by Alfred Hitchcock

A number of films directed by Alfred Hitchcock have been remade, with official remakes of Murder! and The Man Who Knew Too Much being directed by Hitchcock himself. North by Northwest and Saboteur are also considered by some scholars to be unofficial remakes of Hitchcock's English espionage thriller The 39 Steps. This list does not include sequels (such as the films that followed the 1960 version of Psycho), but it does include films based on the same original source materials as were used by Hitchcock (such as the multiple films based on Marie Belloc Lowndes's novel The Lodger).
