Wenden Voivodeship was a unit of administrative division and local government in the Duchy of Livonia, part of the Polish-Lithuanian Commonwealth. It was formed in 1598 by King Zygmunt III Waza, out of Wenden Presidency (Province), which had been created in 1582 by King Stefan Batory, after the Truce of Jam Zapolski. The voivodeship remained in the Commonwealth until the Swedish Empire's conquest of the Livonia in the 1620s. The remainder of Polish Livonia was named Inflanty Voivodeship, and continued to be part of the Commonwealth until the first partition of Poland in 1772.
