Treaty of Andrusovo, 1667 (Polish Rozejm w Andruszowie, Russian Андрусовское перемирие, Ukrainian Андрусівське перемир'я), a truce for 13,5 years between Russia and the Polish-Lithuanian Commonwealth, which were at war since 1654 over the territories of modern day Ukraine and Belarus.

It was signed on January 30 by Afanasy Ordin-Nashchokin (Russia) and Jerzy Chlebowicz (Poland) in a village of Andrusovo not far from Smolensk. Poland agreed to cede the Smolensk and Chernihiv voivodships and acknowledged Russian control over the Left-bank Ukraine (Лівобережна Україна). Right-bank Ukraine (Правобережна Україна) and Belarus remained under Polish control.

The city of Kyiv had to remain with Russia only until 1669, but Russia managed to keep it by signing the Eternal Peace Treaty with Poland in 1686. The region of Zaporozhian Sich was declared to remain under a joint Russo-Polish condominium. The treaty also obliged both sides to common defence against the Ottoman Empire.

In Russia the Treaty of Andrusovo is generally considered an important step towards unification of Ukrainian and Belorussian people with the Russians.
