Mary Kelly (born 1941, Fort Dodge, Iowa) is an American conceptual artist, feminist, educator, and writer.
Kelly has contributed extensively to the discourse of feminism and postmodernism through her large-scale narrative installations and theoretical writings. Kelly's work mediates between conceptual art and the more intimate interests of artists of the 1980s. Her work has been exhibited internationally and she is considered among the most influential contemporary artists working today. Kelly is Judge Widney Professor at the USC Roski School of Art and Design of the University of Southern California. She was previously Professor of Art at the University of California, Los Angeles, where she was Head of Interdisciplinary Studio, an area she initiated for artists engaged in site-specific, collective, and project based work. She was interviewed about her experience teaching at UCLA in Sarah Thornton's Seven Days in the Art World.
