William Benson (1682 – 2 February 1754) was a talented amateur architect and Whig politician who sat in the House of Commons from 1715 to 1719. In 1718, he arranged to displace the aged Sir Christopher Wren as Surveyor of the King's Works, a project in which he had the assistance of John Aislabie, according to Nicholas Hawksmoor, who was deprived of his double post to provide places for Benson's brother.
