Aubrey de Vere, 10th Earl of Oxford (c. 1338 – 23 April 1400) was the third son of John de Vere, 7th Earl of Oxford and Maud de Badlesmere, daughter of Bartholomew de Badlesmere, 1st Lord Badlesmere. Aubrey de Vere had three brothers, John, Thomas, and Robert, and three sisters. Margaret, Maud and Elizabeth. His eldest brother, John, married the daughter of Hugh Courtenay, Earl of Devon, but died in 1350 in his father's lifetime. Another brother, Robert, also died in his father's lifetime. Aubrey de Vere's third brother, Thomas, succeeded his father as 8th Earl of Oxford, and was in turn succeeded by his only son, Robert de Vere, 9th Earl of Oxford, who died in 1392 without issue, leaving Aubrey de Vere to inherit the earldom.
