Elizabeth de Vere (died 14 or 16 August 1375) was the daughter of John de Vere, 7th Earl of Oxford and Maud de Badlesmere,{{sfn|Richardson I|2011|p=542}} and the wife of Sir Hugh Courtenay (died c. 1348), then John de Mowbray, 3rd Baron Mowbray, and then Sir William de Cossington.

Before 3 September 1341 she married Sir Hugh Courtenay (died c. 1348), the eldest son of Hugh Courtenay, 10th Earl of Devon (12 July 1303 – 2 May 1377), and Margaret de Bohun (d. 16 December 1391), daughter of Humphrey Bohun, Earl of Hereford and Essex (c.1276 – 16 March 1322), by Elizabeth (d. 5 May 1316), the daughter of King Edward I.{{sfn|Cokayne|1916|pp=324-5}}{{sfn|Richardson I|2011|pp=239-43, 540-1}}

They had one son, Sir Hugh Courtenay, who died without issue on 20 February 1374.{{sfn|Cokayne|1916|pp=324-5}}{{sfn|Richardson I|2011|p=542}}

Elizabeth de Vere married, secondly, before 4 May 1351, the marriage later being validated by papal dispensation of that date, John de Mowbray, 3rd Baron Mowbray (d. 4 October 1361).{{sfn|Richardson I|2011|p=542}}{{sfn|Richardson III|2011|p=203}}

Not long after the marriage she and her new husband surrendered themselves to the Fleet prison for debt.{{sfn|Cokayne|1936|p=383}}{{sfn|Richardson III|2011|p=203}} According to Archer, the cause may have been her stepson, John de Mowbray, 4th Baron Mowbray's, prosecution of her for waste of his estates; he had been awarded damages against her of almost £1000.{{sfn|Archer|2004}}
