Mary Boone (born c. 1951/1952) is an American art dealer and gallerist, and the owner and director of the Mary Boone Gallery. She played an important role in the New York art market of the 1980s. Her first two artists, Julian Schnabel and David Salle, became internationally known, and in 1982 she had a cover story on New York magazine tagged "The New Queen of the Art Scene." The Mary Boone Gallery has represented artists including Jean-Michel Basquiat, Barbara Kruger, Eric Fischl, Ross Bleckner, and Brice Marden. Originally based in SoHo, Boone operated two galleries, one in midtown on Fifth Avenue, the other in Chelsea. Following her 2019 conviction and sentencing to 30 months in prison for tax evasion, she indicated the intention to close both galleries.
