Sir Thomas Courtenay (1315–1356) was a knight and an English military commander against the French during the Hundred Years' War, who died in the year of the Battle of Poitiers. He was the fourth son of Hugh de Courtenay, 1st/9th Earl of Devon (1276–1340), of Tiverton Castle in Devon, by his wife Agnes de Saint John (d.1340), a daughter of John Saint John (d. 1302) of Basing in Hampshire and a sister of John St John, 1st Baron St John (d. 1329) of Basing. At some time before 27 August 1337 Thomas Courtenay married a great heiress, Muriel de Moels (1322–1369), the elder of the two daughters and co-heiresses of John de Moels, 4th Baron Moels, feudal baron of North Cadbury in Somerset, by his wife Joan Lovel, a daughter of Richard Lovel of Castle Cary in Somerset.
