Admiral of the White Sir William Hargood GCH KCB (6 May 1762 – 12 December 1839) was a British naval officer who served with distinction through the American War of Independence, the French Revolutionary War and the Napoleonic Wars, during which he gained an unfortunate reputation for bad luck, which seemed to reverse following his courageous actions at the battle of Trafalgar in command of HMS Belleisle.
