Julie is a 1956 American thriller starring Doris Day, Louis Jourdan, Barry Sullivan, and Frank Lovejoy. Produced by Day's own Arwin Productions, it is one of the earliest recognized stalker films. Both written and directed by Andrew L. Stone, the picture received two Academy Award nominations, for Best Original Screenplay and Best Song.

The film is among the earliest to feature the subplot of a flight attendant piloting an aircraft to safety, later used in Airport 1975 (1975) and parodied in Airplane! (1980). Julie is also notable for being technically accurate in its use of contemporary aviation technology.
