Stefan Kaczmarz (born 1895 in Sambor, Galicia, Austria-Hungary (now Ukraine) - 1939) was a Polish mathematician. His Kaczmarz method provided the basis for many modern imaging technologies, including the CAT scan.

Kaczmarz was an adjunct professor of mechanics at the Lwow Polytechnic where he collaborated with Stefan Banach.

Some sources claim that Kaczmarz, along with many other members of the Polish intelligentsia, was rounded up by the NKVD after the Soviet invasion of Poland in 1939. Allegedly he, and others who were declared to be the enemies of the Soviet regime, were murdered by the NKVD on orders from the Politburo in 1940 in the Katyń massacre. However, the Polish version of Wikipedia claims that Kaczmarz was not found in any Katyn lists and that he could be killed during combat operations as a porucznik (lieutenant) of Polish Army near Warsaw. Exact place and date of his death are unknown.
