Andrzej Nowacki (born 15 October 1953) is a Polish op art artist who lives and works in Berlin.

In 1977 he left Poland to study Scandinavian languages at the University of Gothenburg and later Art History in Innsbruck, Austria.

Since 1988, the sculptural form of the relief remains the exclusive medium of Nowacki's works.

From 1998, Nowacki's works are inspired by such artists as Max Bill, Josef Albers, Antonio Calderara and Bridget Riley.

Impacted by Malevich and Ilya Chashnik, the square remains the obligatory form for the surface of his reliefs.
