John de Vere, 14th Earl of Oxford, English politician, Lord Great Chamberlain (d. 1526)
John de Vere, 14th Earl of Oxford (14 August 1499 – 14 July 1526) was an English peer and landowner.

By inheritance he was Lord Great Chamberlain of England, and in June 1520, at the age of twenty, he attended King Henry VIII at the Field of the Cloth of Gold.

The young earl was considered a wastrel: in 1523 the king ordered him to moderate his hunting, to eat and drink less, to give up late nights, and to be less extravagant in his dress.

He died at the age of twenty-six.
