Clyde Engineering was an Australian manufacturer of locomotives, rolling stock, and other industrial products. It was founded in September 1898 by a syndicate of Sydney businessmen buying the Granville factory of timber merchants Hudson Brothers. The company won contracts for railway rolling stock, a sewerage system, trams and agricultural machinery. In 1907 it won its first contract for steam locomotives for the New South Wales Government Railways. By 1923 it had 2,200 employees. After contracting during the depression it became a major supplier of munitions during World War II.
