Stanisław Lech Woronowicz (born 22 July 1941, Ukmergė, Lithuania (occupied by Nazi Germany at that time)) is a Polish mathematician and physicist.

It was Woronowicz, and Erling Størmer, who classified positive maps in the low-dimensional cases. This translates to the Peres-Horodecki criterion, in the context of quantum information theory. He is also known for contributions to quantum groups.
