Sir Hugh Allan (September 29, 1810 – December 9, 1882) was a Scottish-Canadian shipping magnate, financier and capitalist. By the time of his death, the Allan Shipping Line had become the largest privately owned shipping empire in the world. He was responsible for transporting millions of British immigrants to Canada, and the businesses that he established from Montreal filtered across every sphere of Canadian life, cementing his reputation as an empire builder. His home, Ravenscrag, was the principal residence of the Golden Square Mile in Montreal.
