Aubrey de Vere, 1st Earl of Oxford (c. 1115 – 26 December 1194) was an English noble involved in the succession conflict between King Stephen and Empress Matilda in the mid-twelfth century. He was the son of Aubrey de Vere, Lord Great Chamberlain and Sheriff of London, and Alice (died c. 1163), a daughter of Gilbert de Clare. At some time between 1144 and 1146, the Constable of Bourbourg arranged a divorce for his daughter Countess Beatrice with Earl Aubrey's consent, after which Oxford ceased to be Count of Guînes.
