Awnsham Churchill (1658–1728) was an English bookseller; he was also a radical Whig politician who sat in the House of Commons from 1705 to 1710. He was the son of William Churchill and Elizabeth Awnsham, and brother of members of Parliament Joshua and William Churchill. Apprenticed to George Sawbridge, Awnsham became a Freeman of the Stationers' Company in 1681. He, with another brother, John, entered business as booksellers and stationers. They were politically engaged, and took part in opposition to James II of England, going so far as to consort with those supporting Monmouth's Rebellion in Amsterdam. Awnsham was arrested in 1687 for printing letters promoting William of Orange's policies of religious toleration. With the rise of William III, however, Churchill would flourish: he became stationer to the King, and a leading bookseller. He became a Whig Member of Parliament for Dorchester in 1705 and 1708. His radicalism led to his defeat in 1710, and a failed 1713 election attempt spelled the end of his political ambitions. Awnsham was friendly with John Locke, served as his publisher, and managed Locke's money and business - becoming his trustee after his death.
