Nord 2.121 to 2.180 were a class of 60 four-cylinder 4-4-0 compound steam locomotives of the Chemins de fer du Nord; they were used as express passenger train locomotives. They were placed in service in 1898 and all but four had been retired by 1933. At the creation of the SNCF in 1938, the surviving locomotives were renumbered 2-220.A.1 to 2-220.A.4
