Christopher Wool is an American artist. Since the 1980s, Wool's art has incorporated issues surrounding post-conceptual ideas. He lives and works in New York City and Marfa, Texas, together with his wife and fellow painter Charline von Heyl.

Wool is best known for his paintings of large, black, stenciled letters on white canvases. Wool began to create word paintings in the late 1980s, reportedly after having seen graffiti on a brand new white truck. Using a system of alliteration, with the words often broken up by a grid system, or with the vowels removed (as in 'TRBL' or 'DRNK'), Wool's word paintings often demand reading aloud to make sense.
