RER NG (French: RER Nouvelle Génération, English: RER New Generation) is a double-deck, dual-voltage electric multiple unit trainset that is currently under construction. Also known as the Class Z 58000 and Class Z 58500, the trainsets are expected to operate on line D and line E of the Réseau Express Régional (RER), a hybrid suburban commuter and rapid transit system serving Paris and its Île-de-France suburbs.

The trainsets were built by a consortium of French manufacturer Alstom and Canadian conglomerate Bombardier. The RER NG is considered to be a part of Alstom's X'Trapolis Duplex platform and is an evolution of several generations of double-deck trainsets built by the consortium, including the Z 2N, MI 2N, and MI 09 series.
