Gare du Nord (French:[ɡaʁdynɔʁ]) is astation onLine 4 andLine 5 of theParis Métro. It is the busiest station in the system (not includingRER stations), with 48 million entrances a year. It is connected to theSNCF railway stationGare du Nord (literally, "North Station", until 1938 run by the well-known companyChemins de Fer du Nord), which is served byRER B,RER D andTransilien Nord commuter trains as well as interurban trains to northern France,Eurostar trains toLondon andThalys trains toBrussels,Amsterdam andCologne. The station is also connected to theLa Chapelle Métro station onLine 2 and to theMagenta RER station onRER E.

On 15 November 1907, Line 5 was extended fromGare d'Orléans (now known as Gare d'Austerlitz) to Gare du Nord where the station was built on a reversing loop. On 21 April 1908, Line 4 was opened fromChâtelet toPorte de Clignancourt through Gare du Nord.
On 5 October 1942, the old Line 5 station was closed and replaced with a through station on 12 October 1942, in preparation for the extension toÉglise de Pantin. The part of the old loop that was not destroyed during the building of RER B in the 1970s, together with connecting lines to Line 2 and Line 4 under theBoulevard de Magenta and Rue de Dunkerque, are now used for driver training (USFRT). The length of platforms on Line 4 were extended from 75 to 90 metres (246 to 295 ft) in the 1960s during the upgrading of the line forrubber-tyre operations.
On 10 December 1981, the RER B station at Gare du Nord opened. The RER D station opened on 27 September 1987 with the rest of the line, whileGare de Magenta on the RER E line opened on 14 July 1999. TheChurch of Saint-Vincent-de-Paul is located nearby.
Access to the station, designed in 1900 by the architectHector Guimard of theCompagnie Générale du Métropolitain de Paris, has been listed as a historic monument since 29 May 1978.

The stations of the two lines are of a standard configuration: they include two platforms flanking two tracks under an elliptical vault. However, the Line 4 station also has a later extension, recognizable by its much higher ceiling and mezzanine.
The platforms of Line 5 are decorated in theAndreu-Motte style: the fittings are orange, but the tiles are white and bevelled. The advertising frames are metallic, and the name of the station is indicated on enamelled plates, inParisine font. Line 4 platforms were raised andplatform screen doors were installed in 2019.
From the station, it is possible, thanks to underground links, to reach theRER B andRER D lines, theGare de Magenta of theRER E and theLa Chapelle of the Line 2.
The station is served by lines 26, 31, 35, 38, 39, 43, 45, 46, 48, 54, 56, 91, 302 and the OpenTour tourist line of theRATP Bus Network and, at night, by lines N01, N02, N14, N43, N44, N140 and N143 of theNoctilien network.
