The Treaty or Truce of Plussa, Pljussa, Plyussa or Narva and Plusa (Russian: Плюсское перемирие, Swedish: Stilleståndsfördrag vid Narva å och Plusa) was a truce between Russia and Sweden, which ended the Livonian War (1558-1583). The truce was signed on 10 August 1583 at the Plyussa River north of the city of Pskov. The truce was set to expire in 1586, but extended in 1585-1586.
Upon the expiration of the truce in 1590, Russia resumed the war against Sweden. Beginning in 1593, Russia and Sweden resumed peace negotiations, which would last for two years. Finally, the two countries signed the Treaty of Teusina (Tyavzino) in 1595.
