The Treaty of Breda (1650) was signed on 1 May 1650 between Charles II, exiled king of England, Scotland and Ireland, and the Scottish Covenanter government. Under its terms, they agreed to install Charles II as King of Scotland and Britain, while Charles undertook to establish a Presbyterian Church of England, and guarantee the rights of the Church of Scotland.

Charles II was King of Scotland from 1649 until 1651 and King of England, Scotland, and Ireland from the 1660 Restoration of the monarchy until his death in 1685.
