Norfolk and Western Class J or the First J Class is a Class of 4-4-0 steam locomotives built for the Shenandoah Valley Railroad and inherited by the Norfolk and Western Railroad when the latter acquired the former. They were built from 1879 at the Baldwin Locomotive Works, in Pennsylvania, and they were retired in 1900 and scrapped by 1901 and 1904.

This was the first "J" class, and was followed by the J class of 1903 and the J class of 1941.
