Admiral Sir John Sutton, KCB (c. 1758 – 8 August 1825) was a Royal Navy officer of the late eighteenth and early nineteenth century who is best known for his service as captain of the ship of the line HMS Egmont during the French Revolutionary Wars, serving with the Mediterranean Fleet in several prominent engagements.

[1] He joined the Royal Navy during the American Revolutionary War as midshipman on board the ship of the line HMS Superb, flagship of Admiral Sir Edward Hughes in the Indian Ocean.

He was wounded in an attack on the navy of Hyder Ali on 8 December 1780 at Mangalore, during the Second Anglo-Mysore War and rewarded with command of the sloop HMS Nymph.

In 1795 Egmont fought at the battles of Genoa and the Hyères Islands, suffering casualties on the latter when a cannon burst.

Sutton moved to HMS Superb shortly afterwards, and in 1801 was appointed Captain of the Fleet under William Cornwallis.
