The six-year Truce of Altmark (or Treaty of Stary Targ, Polish: Rozejm w Altmarku, Swedish: Stillståndet i Altmark) was signed on 26 September [O.S. 16 September] 1629 in the village of Altmark (Stary Targ), in Poland, by the Polish–Lithuanian Commonwealth and Sweden, with help from Richelieu's envoy Charnacé, ending the Polish–Swedish War (1626–1629), and freeing King Gustavus Adolphus of Sweden to enter the Thirty Years' War.
