Pidhirtsi Castle (Ukrainian: Підгорецький замок; Polish: zamek w Podhorcach) is a residential castle-fortress located in the village of Pidhirtsi in Lviv Oblast (province) western Ukraine, located eighty kilometers east of Lviv. It was constructed by Guillaume Le Vasseur de Beauplan between 1635–1640 by order of the Polish-Lithuanian Commonwealth's Grand Crown Hetman Stanisław Koniecpolski, on the place of the older fortress. The castle was then part of the Kingdom of Poland and it is regarded as the most valuable of palace-garden complexes in the eastern borderlands (Kresy Wschodnie) of the former Polish-Lithuanian Commonwealth.
