Sweet Liberty is a 1986 American comedy film written and directed by Alan Alda, and starring Alda in the lead role, alongside Michael Caine and Michelle Pfeiffer, with support from Bob Hoskins, Lois Chiles, Lise Hilboldt, Lillian Gish, and Larry Shue.

The story was partly inspired by Alda's experiences while caring for his parents who had both been ill and were in two different hospitals. During a visit to see his dying father, a nurse approached him with a head shot and résumé. In an interview prior to the film's UK release he said, "It was the worst year of my life and I thought this is so miserable there must be a funny movie in it!".

Sweet Liberty featured the penultimate film appearance of Lillian Gish; she had made her screen debut 74 years earlier, in 1912.
