The GWR Castle Class is a class of British steam locomotives introduced by the Great Western Railway in 1923, designed to haul the railway's principal express passenger trains and considered, alongside its larger King Class successor, among the most powerful express passenger locomotives in Britain at the time of introduction. Members of the class remained in mainline service into the 1960s and several examples survive in preservation.
