Count Wilhelm Kinsky von Wchinitz (Czech: Vilém Kinský z Vchynic; German: Wilhelm Graf Kinsky von Wchinitz und Tettau; 1574 – 25 February 1634) was a Czech landowner and a statesman.
By birth, he was member of the House of Kinsky, which belonged to the highest circle of Bohemian aristocracy.
As a rich landowner in Bohemia, Kinsky lived in exile at Dresden after the Battle of White Mountain, because he was a Protestant and, unlike the members of the Trčka family, had refused to convert to the Catholic faith but was allowed to regularly visit his Bohemian estates.
Subsequently, together with his brother-in-law Adam Erdmann Trčka, he attempted to pull Wallenstein over to the Protestant and Swedish side.
Kinsky was assassinated during the Thirty Years' War, on 25 February 1634 at Cheb, together with Trčka and other officers loyal to the general and the Field Marshal himself, during the so-called Eger Bloodbath,[1] a plot to purge the Imperial Army from Albrecht von Wallenstein's supporters.
