The London and North Western Railway (LNWR) Class G2 is a class of 0-8-0 steam locomotives. 60 were built at Crewe Works in 1921–1922. Uniquely amongst classes of LNWR 8-coupled tender engines, they were not rebuilt from or into other classes. Slightly confusingly the LNWR Class G2a is sometimes considered a subclass, but not in this article. They were classified by the London, Midland and Scottish Railway (LMS) as 5, from 1928 7F.
