Claude Albo de Bernales (31 May 1876 – 9 December 1963) was a Western Australian mining entrepreneur whose business activities and marketing did much to stimulate investment in Western Australia during the early years of the twentieth century. During the 1930s gold production in the State increased from £1,600,000 to £11,800,000 and employment in the industry quadrupled due in considerable part to de Bernales' marketing of the goldfields to overseas investors.
