RER B is one of the five lines in the Réseau Express Régional (English: Regional Express Network), a hybrid suburban commuter and rapid transit system serving Paris, France and its Île-de-France suburbs. The 80 km (50 mi) RER B line crosses the Paris region from north to south, with all trains serving a group of stations in central Paris, before branching out towards the ends of the line.

The line opened in stages starting in December 1977 by connecting two existing suburban commuter rail lines with a new tunnel under Paris: the Chemin de Fer du Nord to the north (which formerly terminated at Gare du Nord) and the Ligne de Sceaux to the south (which formerly terminated at Luxembourg station).

The RER B, along with the rest of the RER network, has had a significant social impact on Paris and the surrounding region by speeding up trips across central Paris, by making far fewer stops than the Paris Métro and by bringing far-flung suburbs within easy reach of the city centre. The line has far exceeded all traffic expectations, with passengers taking 165 million journeys per year in 2004. That makes the RER B the second busiest single rail line in Europe.

The line faces capacity challenges as a result of sharing a tunnel with RER D trains between Châtelet–Les Halles and Gare du Nord.
