Maxwell & Demon Gargoyle is an outdoor 1989 sculpture by Wayne Chabre, installed in Eugene, Oregon, in the United States. It is a low-relief portrait depicting Scottish physicist James Clerk Maxwell and his "demon", attached to the exterior of Willamette Hall on the University of Oregon campus. The hammered copper sheet sculpture measures approximately 3.15 feet (0.96 m) x 2.5 feet (0.76 m) x 1.5 feet (0.46 m). Its condition was undetermined when the Smithsonian Institution's "Save Outdoor Sculpture!" program surveyed the work in 1994.
