William York Wray, known professionally as Bill Wray, is an American cartoonist, animator and landscape painter widely known for his contributions to Mad and The Ren & Stimpy Show, as well as his current focus on regional landscape painting—under the names Bill Wray for his animated work and William Wray for his paintings.

With urban landscapes, cartoon elements, and superheroes as frequent subjects, Wray is noted for a tightly cropped and abstract painting style. The Huffington Post said he "has a brisk, bold style that gives his city scenes a jolt of painterly drama." Southwest Art Magazine called him "a chronicler of the fading urban remains of a bygone era."
