Barry Railway Class J were 2-4-2T steam tank locomotives of the Barry Railway in South Wales. They were designed by J. F. Hosgood, built by both Hudswell Clarke and Sharp, Stewart and Company and were introduced in 1897. Their main use was on the Barry to Cardiff suburban service and had a reputation for always being smartly turned out. They were all shedded at Barry. The locomotives passed to the Great Western Railway in 1922. None survived into British Railways ownership and none have been preserved.
