John Leake, Royal Navy admiral (d. 1720)
Admiral of the Fleet Sir John Leake (4 July 1656 – 21 August 1720) was a Royal Navy officer and politician. As a junior officer he saw action at the Battle of Texel during the Third Anglo-Dutch War. He then distinguished himself when he led the convoy that broke the barricading boom at Culmore Fort thereby lifting the siege of Derry during the Williamite War in Ireland. As a captain he saw action in some of the heaviest fighting (70 of his men were killed) at the Battle of Barfleur and was also involved in a successful attack on the French ships at the Battle of La Hogue during the Nine Years' War.

Leake went on to be Commander-in-Chief, Newfoundland and then, as a flag officer, served as Second-in-Command to Admiral George Rooke at the Capture of Gibraltar and he commanded the vanguard in the Battle of Málaga during the War of the Spanish Succession. He later returned to Gibraltar with a combined English, Dutch and Portuguese force of 35 ships and defeated Baron de Pointis at the Battle of Cabrita Point.

Leake also served under Sir Cloudesley Shovell and the Earl of Peterborough at the siege of Barcelona and was present at the capitulation of the city by French and Spanish forces. A further siege took place between when a Franco-Spanish army led by Philip V of Spain laid siege to Barcelona in an attempt to recapture it. The Franco-Spanish army abandoned the siege when Leake arrived. Leake later captured Sardinia and landed the Earl of Stanhope with forces that took the well-fortified harbour of Port Mahon on Minorca.

Leake served as Member of Parliament for Rochester from 1708 to 1715 and as First Lord of the Admiralty from 1710 to 1712.
