Mamet is the daughter of American playwright, essayist, screenwriter, and film director David Mamet and actress Lindsay Crouse. Her father is the grandson of Polish Jews[3] and she says her given name is Polish and Russian.[4] Her father is Jewish and her mother is Buddhist, and Mamet identifies as Jewish as well.[citation needed] Her maternal grandfather was playwright Russel Crouse and her maternal great-grandfather was educator John Erskine. She has a sister, Willa, who is a singer, and two half-siblings: Clara, also an actress and director; and Noah. She lived in New England until age five when her mother moved to Pacific Palisades, California, with Willa and Zosia.[5] After finishing high school, Mamet decided to pursue acting instead of going to college.[6]
At the 2017 Makers Conference, Mamet performed a monologue describing her experience of living with undiagnosed pelvic floor dysfunction for six years.[12][13]
