The Kiev Voivodeship (Polish: Województwo kijowskie, Ukrainian: Київське воєводство) was a unit of administrative division and local government in the Grand Duchy of Lithuania from 1471 until 1569 and of the Crown of the Kingdom of Poland from 1569 until 1793 as part of Lesser Poland Province of the Polish Crown.
It was the biggest voivodeship of the Polish-Lithuanian Commonwealth, covering, among others, land of Zaporizhian Cossacks. Under the order of King Casimir Jagiellon, it had replaced the former Principality of Kiev, ruled by Lithuanian princes, from two families (House of Algirdas and Olshansky family). Its first administrative center was Kiev, but when the city was given to Imperial Russia in 1667 by Treaty of Andrusovo, the capital moved to Zhytomyr (Żytomierz), where it remained until 1793.
