Sir Edward Courtenay (c.1385 – c. August 1418) was the eldest son of Edward de Courtenay, 11th Earl of Devon (d. 5 December 1419). He fought at Agincourt, and was killed in a sea battle in Henry V's continuing campaigns in Normandy.

Born about 1385, Sir Edward Courtenay was the eldest son and heir of Edward Courtenay, 11th Earl of Devon (d. 5 December 1419), and Maud Camoys, the daughter of Sir John de Camoys of Gressenhall, Norfolk by his second wife, Elizabeth le Latimer, the daughter of William le Latimer, 3rd Lord Latimer. Courtenay had two younger brothers, Hugh Courtenay, 12th Earl of Devon, and James Courtenay, and a sister, Elizabeth Courtenay, who married firstly John Harington, 4th Baron Harington (d. 11 February 1418), and secondly William Bonville, 1st Baron Bonville (d. 18 February 1461).

Before 20 November 1409 Courtenay married Eleanor Mortimer, daughter of Roger de Mortimer, 4th Earl of March, and Eleanor Holland. Courtenay's sister-in-law, Anne Mortimer, was born at New Forest, Westmeath, one of the Mortimer estates in Ireland, and it is likely Eleanor Mortimer was born there as well. Besides her sister, Anne, Eleanor Mortimer had two brothers, Edmund Mortimer, 5th Earl of March, and Roger (born 23 April 1393, died c.1413).

Eleanor Mortimer's mother was the daughter of Thomas Holland, 2nd Earl of Kent, and Alice Arundel, the daughter of Richard de Arundel, 10th Earl of Arundel, and his second wife, Eleanor, daughter of Henry, 3rd Earl of Lancaster, grandson of King Henry III.
