Birdman of Alcatraz is a 1962 American biographical drama film directed by John Frankenheimer and starring Burt Lancaster. It is a largely fictionalized version of the life of Robert Stroud, who was sentenced to solitary confinement after having killed a prison guard. A federal prison inmate, he became known as the "Birdman of Alcatraz" because of his studies of birds, which had taken place when he was incarcerated at Leavenworth Prison where he was allowed to keep birds in jail. Although known as "The Birdman of Alcatraz", Stroud was never allowed to keep any birds after his transfer to Alcatraz Federal Penitentiary in 1942.

The film was adapted by Guy Trosper from the 1955 book by Thomas E. Gaddis. It was nominated for Academy Awards for Best Actor in a Leading Role (Burt Lancaster), Best Actor in a Supporting Role (Telly Savalas), Best Actress in a Supporting Role (Thelma Ritter), and Best Cinematography, Black-and-White.
