The Treaty of Seville was signed on 9 November 1729 between Britain, France, and Spain, formally ending the 1727–1729 Anglo-Spanish War; the Dutch Republic joined the Treaty on 29 November.

The Anglo-Spanish War of 1727–1729 was a limited war that took place between Great Britain and Spain during the late 1720s, and consisted of a failed Spanish attempt to capture Gibraltar and an unsuccessful British Blockade of Porto Bello. It eventually ended with a return to the previous status quo ante bellum following the Treaty of Seville.
