Albert James Hill (April 7, 1836 - November 26, 1918), generally known as A.J. Hill, was an esteemed Canadian land surveyor and civil engineer who was closely associated with railways. Aside from being born on Cape Breton Island, other details of his life are obscure. He may have been a relation of Canadian railway magnate James Jerome Hill (1838 - 1916). In any event, he was a prominent surveyor on the Canadian Pacific Railway and New Westminster Southern Railway, as well as a provincial land surveyor, in the course of his career. He also served as a director of the Coquitlam Water Works Company in British Columbia and became involved in local politics.
