Grey Gardens is a 1975 American documentary film by Albert and David Maysles. The film depicts the everyday lives of two reclusive, upper-class women, a mother and daughter both named Edith Beale, who lived in poverty at Grey Gardens, a derelict mansion at 3 West End Road in the wealthy Georgica Pond neighborhood of East Hampton, New York. The film was screened at the 1976 Cannes Film Festival but was not entered into the main competition.

Ellen Hovde and Muffie Meyer also directed, and Susan Froemke was the associate producer. The film was edited by Hovde, Meyer and Froemke.

In 2010, the film was selected by the Library of Congress for preservation in the United States National Film Registry as being "culturally, historically, or aesthetically significant", and in the 2014 Sight and Sound poll film critics voted Grey Gardens the tenth-best documentary film of all time. In November 2012, it topped the list of 100 greatest documentary films of all time by PBS through public voting.
