North by Northwest was nominated for three Academy Awards—for Best Film Editing (George Tomasini), Best Art Direction – Set Decoration, Color (William A. Horning, Robert F. Boyle, Merrill Pye, Henry Grace, Frank McKelvy), and Best Original Screenplay (Ernest Lehman)—at the 32nd Academy Awards ceremony. Two of the three awards went instead to Ben-Hur, and the other went to Pillow Talk. The film also won a 1960 Edgar Award for Best Motion Picture Screenplay, for Lehman.
In 1995, North by Northwest was selected for preservation in the National Film Registry by the United States Library of Congress as being "culturally, historically, or aesthetically significant."
