John de Vere, 15th Earl of Oxford, Lord Great Chamberlain KG PC (c.1482 – 21 March 1540) was an English peer and courtier.

John de Vere, born about 1482, was the son of John de Vere and Alice Kilrington (alias Colbroke), and the great-grandson of Richard de Vere, 11th Earl of Oxford, succeeding his second cousin, John de Vere, 14th Earl of Oxford, in the earldom. De Vere had two stepbrothers, William Courtenay and Walter Courtenay, and a stepsister, Katherine Courtenay, by his mother's second marriage, before 1491, to Sir Walter Courtenay (d. 7 November 1506), a younger son of Sir Philip Courtenay of Powderham, Devon, by Elizabeth Hungerford.

De Vere was an Esquire of the Body at the funeral of Henry VII in 1509, and was knighted by Henry VIII 25 September 1513 at Tournai, following the Battle of the Spurs. He attended Henry VIII at the Field of the Cloth of Gold in 1520, and at his meeting with the Holy Roman Emperor, Charles V, at Dover in 1522.

On 19 December 1526 Oxford was appointed Lord Great Chamberlain for life and was made a Knight of the Garter on 21 October 1527. He signed the Lords' petition against Cardinal Wolsey on 1 December 1529, and was appointed to the Privy Council before 22 March 1531.

In 1531 it was reported from Venice that Oxford was 'a man of valour and authority … and it is his custom always to cavalcade with two hundred horse’.
