The Treaty or Peace of Oliva of 23 April (OS)/3 May (NS) 1660 was one of the peace treaties ending the Second Northern War (1655–1660). The Treaty of Oliva, the Treaty of Copenhagen in the same year, and the Treaty of Cardis in the following year marked the high point of the Swedish Empire.

The Second Northern War (1655–60), was fought between Sweden and its adversaries the Polish–Lithuanian Commonwealth (1655–60), the Tsardom of Russia (1656–58), Brandenburg-Prussia (1657–60), the Habsburg monarchy (1657–60) and Denmark–Norway. The Dutch Republic waged an informal trade war against Sweden and seized the colony of New Sweden in 1655, but was not a recognized part of the Polish–Danish alliance.
