The GWR 4073 Class, or Castle class, locomotives were a group of 4-6-0 steam locomotives of the Great Western Railway. They were originally designed by the railway's Chief Mechanical Engineer, Charles Collett, for working the company's express passenger trains. As a development of the earlier Star Class, 171 were built, over a 25 year span from August 1923 to August 1950. They were numbered 4073–4099; 5000–5099 and 7000–7037.
Although most were built new, sixteen locos were rebuilt from older locomotives (fifteen Star Class locomotives); and the Great Western Railway's sole 4-6-2 locomotive, number 111 The Great Bear.
Withdrawal started in the 1950s; the last to be withdrawn was Clun Castle at the end of 1965. Eight Castles survive in preservation.
