Frances Ann Lebowitz (/ˈliːbəwɪts/; born October 27, 1950) is an American author, public speaker, cultural critic, and actor. She is known for her sardonic social commentary on American life as filtered through her New York City sensibilities and her association with many prominent figures of the New York art scene of the 1970s and 1980s, including Andy Warhol, Martin Scorsese, Jerome Robbins, Robert Mapplethorpe, David Wojnarowicz, Candy Darling, and the New York Dolls.

Lebowitz gained fame for her books Metropolitan Life (1978) and Social Studies (1981), which were combined into The Fran Lebowitz Reader in 1994. She has been the subject of two projects directed by Martin Scorsese, the HBO documentary film Public Speaking (2010), and the Netflix docu-series Pretend It's a City (2021).
