Julie Heffernan (born 1956 in Peoria, Illinois) is an American painter.
David Cohen, art critic of The New York Sun, aptly describes Heffernan's art: "These paintings are a hybrid of genres and styles, mixing allegory, portraiture, history painting, and still life, while in title they are all presented as self portraits."
Heffernan was raised in Northern California and lives in Brooklyn, New York. She received a B.F.A., at the University of California, Santa Cruz and an M.F.A. in painting at the Yale School of Art. Heffernan is an Associate Professor of fine arts at Montclair State University in Upper Montclair, New Jersey.
