Sir Henry Arthur Colefax, KC (9 July 1866 – 19 February 1936) was a British patent lawyer and Conservative Party politician. Colefax was born in Bradford, Yorkshire, and was the son of J S Colefax, a woollen merchant. He was initially educated at Bradford Grammar School before studying natural science and chemistry at the University of Strasbourg, and at Merton and Christ Church Colleges at the University of Oxford. In 1894 he was called to the bar at Lincoln's Inn, and quickly became an acknowledged expert on patent law. He was made a King's Counsel in 1912.
