Richard Anuszkiewicz (born 1930, Erie, Pennsylvania) is an op art painter, sculptor, and printmaker. Most of his work comprises visual investigations of formal structural and colour effects, many of them nested square forms similar to the work of Josef Albers.

Anuszkiewicz trained at the Cleveland Institute of Art in Cleveland, Ohio (1948–53), and then with Josef Albers at the Yale University School of Art and Architecture in New Haven, Connecticut (1953–5).
