William Lygon, 7th Earl Beauchamp KG, KCMG, PC (1872–1938), was a British Liberal politician. He was Governor of New South Wales between 1899 and 1901, a member of the government under Sir Henry Campbell-Bannerman and H H Asquith between 1905 and 1915, and leader of the Liberal Party in the House of Lords between 1924 and 1931.
