Jeremiah Coghlan CB (c. 1776 – 4 March 1844) was a British naval officer. He was famous for his almost legendary feats of daring during the French Revolutionary and Napoleonic Wars. Despite his relatively humble background, he managed to rise from ship's boy to the rank of captain at the age of 34. This he achieved through notable acts of extraordinary courage and a succession of sea-fights which made him a celebrated hero, almost without equal, and he would later dine with both Nelson and Napoleon. Coghlan's career was initiated by his patron and close friend Sir Edward Pellew, after Pellew witnessed his heroic efforts during the rescue of the survivors of the East Indiaman Dutton.
