A French invasion of Great Britain was planned to take place in 1759 during the Seven Years' War, but due to various factors was never launched. The French planned to land 100,000 French soldiers in Britain to end British involvement in the war. The invasion was one of several failed French attempts during the 18th century to invade Britain.

The Battle of Quiberon Bay was a decisive naval engagement during the Seven Years' War. It was fought on 20 November 1759 between the Royal Navy and the French Navy in Quiberon Bay, off the coast of France near Saint-Nazaire. The battle was the culmination of British efforts to eliminate French naval superiority, which could have given the French the ability to carry out their planned invasion of Great Britain. A British fleet of 24 ships of the line under Sir Edward Hawke tracked down and engaged a French fleet of 21 ships of the line under Marshal de Conflans. After hard fighting, the British fleet sank or ran aground six French ships, captured one and scattered the rest, giving the Royal Navy one of its greatest victories, and ending the threat of French invasion for good.
