Tourcoing (French pronunciation: ​[tuʁ.kwɛ̃]) is a city in northern France. It is designated municipally as a commune within the département of Nord. Located to the north-northeast of Lille, adjacent to Roubaix, Tourcoing is the chef-lieu of two cantons and the fourth largest city in the French region of Nord-Pas-de-Calais-Picardie ranked by population with about 94,000 inhabitants.

Together with the cities of Lille, Roubaix, Villeneuve-d’Ascq and eighty-one other communes, Tourcoing is part of four-city-centred metropolitan area inhabited by around 1.1 million people: the European Metropolis of Lille.[1][2] To a greater extent, Tourcoing belongs to a vast conurbation formed with the Belgian cities of Mouscron, Kortrijk and Tournai, which gave birth to the first European Grouping of Territorial Cooperation in January 2008, Lille–Kortrijk–Tournai with an aggregate of just over 2 million inhabitants.[3]
