Vice-Admiral Sir William Charles Fahie KCB (1763 – 11 January 1833) was a prominent British Royal Navy officer during the American War of Independence, French Revolutionary War and the Napoleonic Wars. Unusually, Fahie's service was almost entirely spent in the West Indies, where he had been born and where he lived during the time he was in reserve and in his retirement. After extensive service in the Caribbean during the American War of Independence, during which Fahie impressed with his local knowledge, Fahie was in reserve between 1783 and 1793, returning to service to participate in Sir John Jervis' campaign against the French West Indian islands in 1794.
