Republic of Pińczów (Polish: Republika Pińczowska) was a name of short-lived entity (1000 km²) in Świętokrzyskie Voivodeship liberated by joint forces of Polish Resistance formations: Home Army, People's Army and Peasants' Battalions, during a period from July 21 to August 12, 1944.
Power in the Republic belonged to delegate of Polish Government in Exile and local commander of the Home Army Forces. There was also a separate authority, which composed communist forces.
The Republic collapsed due to concentration of Wehrmacht nearby and lack of supplies.
