Neil Williams (1934 – March 28, 1988) was an American painter. Williams was an abstract painter primarily known for his pioneering work with shaped canvases in the early 1960s. His paintings of the 1960s, 1970s and 1980s are associated with geometric abstraction, hard-edge painting, color field, and lyrical abstraction, although he did not readily subscribe to any category for his work. He taught Fine Arts at the School of Visual Arts from the late 1970s until the early 1980s.
