Państwowy Korpus Bezpieczeństwa (Polish for National Security Corps, short PKB) was a Polish underground police force organized by the Armia Krajowa and Delegate's Office under German occupation during World War II. It was trained as the core of the future police forces during the assumed all-national uprising and after the liberation. The first commander of the Corps was lt. col. Marian Kozielewski . He was later replaced by Stanisław Tabisz . In October 1943 the PKB had 8 400 officers, until early 1944 the number grew to almost 12 000.

The PKB was created by the Department of the Internal Affairs of the Delegate's Office in 1940, mostly from members of the pre-war Polish police and volunteers. PKB carried out investigation and criminal intelligence duties as well as gathered reports of the Gestapo and Kripo in the General Government. It enforced the verdicts prepared by the Directorate of Civil Resistance and Directorate of Underground Resistance and passed by the Special Courts.
