Earl of Oxford is a dormant title in the Peerage of England, first created for Aubrey de Vere by the Empress Matilda in 1141. His family was to hold the title for more than five and a half centuries, until the death of the 20th Earl in 1703. The de Veres were also hereditary holders of the office of Master Chamberlain of England from 1133 until the death of the 18th Earl in 1625. Their primary seat was Hedingham Castle in Essex, but they held lands in southern England and the Midlands, particularly in eastern England. The actual earldom was called "Oxenford" until at least the end of the 17th century. Medieval sources thus refer to "my lord of Oxenford" when speaking of the earl.

The Lord Great Chamberlain of England is the sixth of the Great Officers of State, ranking beneath the Lord Privy Seal but above the Lord High Constable. The office of Lord Great Chamberlain is an ancient one, being first created circa 1126 in Norman times and in continuous existence since 1138. The incumbent is Rupert Carington, 7th Baron Carrington.
