J. Mack is a Brooklyn-based visual artist whose constructed portraiture examines family mythology, domestic performance, gender, and the uneasy fictions of American normalcy.

Born in Detroit in 1982, J. Mack graduated from Parsons School of Design in 2005, received the Tierney Fellowship the same year, and joined Laurence Miller Gallery, where her early work was exhibited as Julie Mack. By her late twenties, her photographs had been shown at Art Basel, Paris Photo at the Louvre, and ARCO Madrid, and her work had been acquired by the Museum of Fine Arts, Boston, where it is held in the permanent collection. She was shortlisted for the Paris Photo Prize for Contemporary Photography, and her photographs have appeared in LIFE, Time, The New York Times, New York Magazine, and Condé Nast Traveler.

From 2008 to 2024, J. Mack worked across commercial filmmaking, art direction, and creative leadership, co-founding the production studio THEY bklyn. Throughout that period, she continued photographing her family, building an unfinished body of work she has carried with her for two decades.

As a gender-nonconforming queer artist embedded within a white, heteronormative family, J. Mack works at the intersection of belonging and critique. She is now returning to a full-time studio practice, with a renewed focus on staged portraiture, the visual codes of belonging, and the unstable beauty of inherited roles.
