Louise Lawler (born 1947, Bronxville, New York) is a U.S. artist and photographer. From the late 1970s onwards, Lawler's work has focused on the presentation and marketing of artwork. Much of this work consists of photographs of other peoples' artwork and the context in which it is viewed. Examples of Lawler's photographs include images of paintings hanging on the walls of a museum, paintings on the walls of an art collector's opulent home, artwork in the process of being installed in a gallery, and sculpture in a gallery being viewed by spectators.
Along with photography, she has created conceptual and installation art. Some of her works, such as the "Book of Matches", are ephemeral and explore the passing of time, while others, such as "Helms Amendment (963)," are expressly political.
