Burgoyne A. Diller (January 13, 1906 – January 30, 1965) was an American abstract painter. Many of his best-known works are characterized by orthogonal geometric forms that reflect his strong interest in the De Stijl movement and the work of Piet Mondrian in particular. Overall, his Geometric abstraction and non-objective style also owe much to his study with Hans Hofmann at the Art Students League of New York. He was a founding member of the American Abstract Artists. Diller's abstract work has sometimes been termed "constructivist". He also did figurative and representational works early in his career working as a muralist for the New York City Federal Arts Project.
