Colen Campbell (15 June 1676 – 13 September 1729) was a pioneering Scottish architect and architectural writer, credited as a founder of the Georgian style. For most of his career, he resided in Italy and England. A descendant of the Campbells of Cawdor Castle, he is believed to be the Colinus Campbell who graduated from the University of Edinburgh in July 1695. He initially trained as a lawyer, being admitted to the Faculty of Advocates on 29 July 1702.
