John Ipstones (died 1394) was an English soldier, politician and landowner. He fought in the Hundred Years War and in John of Gaunt's expedition to win the Crown of Castile. He represented Staffordshire twice in the House of Commons of England, including the Merciless Parliament of 1388, in which he supported the measures of the Lords Appellant. A member of a notoriously quarrelsome and violent landed gentry family, he pursued numerous property and personal disputes, one of which led to his murder while in London, serving as a Member of Parliament.
