Sir Allen Apsley, 28 August 1616 to 15 October 1683, was a Royalist soldier and administrator during the Wars of the Three Kingdoms, who took part in the Second Anglo-Dutch War. He was also MP for Thetford from 1661 to 1679. One biographer describes him as having an "ability to maintain friendly contact with figures across a wide range of affiliations, which helped to make him a successful political fixer". He became treasurer for James, Duke of York and his political manager in the Commons until losing office in 1679. He died in October 1683 and was buried in Westminster Abbey.
