The Polish–Russian Peace Treaty of 1686, officially known as Treaty of Perpetual Peace , , but also known in Polish tradition Grzymułtowski Peace, ) was concluded between Russia and Poland–Lithuania to finally end the Russo-Polish War of 1654–1667. It was signed in Moscow on 6 May 1686 by Polish–Lithuanian envoys Krzysztof Grzymułtowski, Voivode of Poznań and Marcjan Ogiński, Chancellor of Lithuania, as well as the Russian knyaz Vasily Vasilyevich Golitsyn. These parties were incited to cooperate after a major geopolitical intervention in the southern regions of Zaporozhie on the part of the Ottoman Empire.
The treaty confirmed the earlier Truce of Andrusovo of 1667. The legal legitimacy of its ratification has been disputed. According to Jacek Staszewski, the treaty was not confirmed by a resolution of the Sejm until the Convocation Sejm of 1764.
The borders between Russia and the Commonwealth established by the treaty remained in effect until the First Partition of Poland in 1772.
