Peter Halley (born 1953) is an American artist, writer, and educator known for his vibrant, geometric, Day-Glo paintings and his role in the 1980s Neo-Conceptualist movement. His abstract work uses barred cells and grid-like structures to critique modern society’s consumerism and control, and he has also worked with Roll-a-Tex textured paint and published the influential Index Magazine. Halley holds degrees from Yale University and the University of New Orleans, and he has held a prominent teaching position at the Yale University School of Art.
