Marcadet - Poissonniers is a station of the Paris Métro, serving Line 4 and Line 12. Fare Zone: 1.

Previously, there were two stations. Marcadet on Line 4 (operated by the CMP) opened on 21 April 1908 as part of the first section of the line from Châtelet to Porte de Clignancourt. The name Marcadet is taken from the Rue Marcadet (from the Latin mercadus, "market"), which name appears on medieval maps, and from the Rue des Poissonniers, used since the Middle Ages by fishmongers (French: poissonniers) to bring fish from the North Sea to the markets at Les Halles.
