Sir John Trevor (1626-28 May 1672), English politician, was a son of Sir John Trevor (d. 1673) of Trevelyn, Denbighshire. His father was a member of parliament under James I and Charles I, and sat also in the parliaments of Oliver and of Richard Cromwell, and was a member of the council of state during the Commonwealth. One of his uncles was Sir Sackvill Trevor (d. c. 1640), a naval officer, who was knighted in 1604; and another was Sir Thomas Trevor (1586-1656), the judge who decided in favor of the Crown in the famous case about the legality of ship-money, and was afterwards impeached and fined. Sir John Trevor was returned to parliament in 1646 as member for Flintshire. After filling several public positions under the Commonwealth and Protectorate he was a member of the council of state appointed in February 1660 and under Charles II he rose to a high position. Having purchased the office of Secretary of State he was knighted and entered upon its duties towards the end of 1668, just after he had helped to arrange an important treaty between England and France, serving until his death four years later. He married Ruth, daughter of the great John Hampden.
