John Cooke (c.1762 – 21 October 1805) was an experienced and highly regarded officer of the Royal Navy during the American War of Independence, the French Revolutionary Wars and the first years of the Napoleonic Wars. Cooke is best known for his death in hand-to-hand combat with French forces during the Battle of Trafalgar in 1805. During the action, his ship HMS Bellerophon was badly damaged and boarded by sailors and marines from the French ship of the line Aigle. Cooke was killed in the ensuing melee, but his crew successfully drove off their opponents and ultimately forced the surrender of Aigle.
