The Battle of Minorca (20 May 1756) was a naval battle between French and British fleets. It was the opening sea battle of the Seven Years' War in the European theatre. Shortly after the war began British and French squadrons met off the Mediterranean island of Minorca. The French won the battle. The subsequent decision by the British to withdraw to Gibraltar handed France a strategic victory and led directly to the Fall of Minorca.

The British failure to save Minorca led to the controversial court-martial and execution of the British commander, Admiral John Byng, for "failure to do his utmost" to relieve the siege of the British garrison on Minorca.
