No Peace Without Spain was a popular British political slogan of the early eighteenth century. It referred to the ongoing War of the Spanish Succession (1701–1714) in which Britain was a leading participant. It implied that no peace treaty could be agreed with Britain's principal enemy Louis XIV of France that allowed Philip, the French candidate, to retain the Spanish crown. The term became a rallying cry for opposition to the Tory government of Robert Harley, Earl of Oxford and the terms of the Treaty of Utrecht.

The Peace of Utrecht was a series of peace treaties signed by the belligerents in the War of the Spanish Succession, in the Dutch city of Utrecht between April 1713 and February 1715. The war involved three contenders for the vacant throne of Spain, and involved much of Europe for over a decade. The main action saw France as the defender of Spain against a multinational coalition. The war was very expensive and bloody, and finally stalemated. Essentially, the treaties allowed Philip V to keep the Spanish throne in return for permanently renouncing his claim to the French throne, along with other necessary guarantees that would ensure that France and Spain should not merge, thus preserving the balance of power in Europe.
