The Nazis and Nazi Collaborators (Punishment) Law (Hebrew: חוק לעשיית דין בנאצים ובעוזריהם, תש"י-1950) is a 1950 Israeli law passed by the First Knesset that provides a legal framework for the prosecution of crimes against Jews and other persecuted people committed in Nazi Germany, German-occupied Europe, or territory under the control of another Axis power between 1933 and 1945. The law's primary target was Jewish Holocaust survivors alleged to have collaborated with the Nazis, in particular prisoner functionaries ("kapos") and the Jewish Ghetto Police. It was motivated by the anger of survivors against perceived collaborators and a desire to "purify" the community.
