William Markham (1710-1807), English divine and archbishop of York, was educated at Westminster and at Christ Church College, Oxford.

He was one of the best scholars of his day, and attained to the headship of his old school and college in 1753 and 1767 respectively. He held from time to time a number of livings, and in 1771 was made bishop of Chester and tutor to George prince of Wales. In 1776 he became Archbishop of York, and also lord high almoner and privy councillor.

He was a firececritic of pamphleteer Richard Price concerning the American rebellion. He was for some time a close friend of Edmund Burke, but his strong championship of Warren Hastings caused a breach. He was accused by Lord Chatham of preaching pernicious doctrines, and was a victim of the Gordon riots in 1780.
