The Truce of Andrusovo (Polish: Rozejm w Andruszowie, Russian: Андрусовское перемирие, Andrusovskoye Pieriemiriye, also sometimes known as Treaty of Andrusovo) established a thirteen-and-a-half year truce, signed in 1667 between Tsardom of Russia and the Polish–Lithuanian Commonwealth, which had fought the Russo-Polish War since 1654 over the territories of modern-day Ukraine and Belarus.
