Thomas Moore Manby (January 1, 1769 – June 13, 1834) was a British naval officer who fights in the French Revolutionary Wars and Napoleonic Wars and later rises to the rank of rear admiral.
He sails with George Vancouver on his voyages of exploration, captains Bordelais, Africaine and Thalia, and is the chief suspect in the "delicate investigation" into the morals of Caroline, Princess of Wales.
