{{main|Derby du Nord}}

The ''[[Derby du Nord]]'' ([[French language|French]] for "The North Derby") is contested between Lille and [[RC Lens]]. The derby name refers only to their geographical location in France; both clubs and cities only being located in the northern part of France, within the [[Hauts-de-France]] region but not the same [[Departments of France|department]]. Being the fourth-largest city of the [[Pas-de-Calais]] department, [[Lens, Pas-de-Calais|Lens]] is located 30 kilometres south of regional prefecture and nerve centre [[Lille]], [[Nord (French department)|Nord]] department main city. The name can also refer to matches involving Lille and [[Valenciennes FC|Valenciennes]] as both clubs are located within Nord, however, the match historically refers to matches involving Lille and Lens. As a result, the Lille–Valenciennes match is sometimes referred to as ''Le Petit Derby du Nord'' (French for "The Little North Derby").

The two clubs first met in 1937 when Lille were playing under the [[Olympique Lillois]] emblem. Due to each club's close proximity towards each other being separated by only {{convert|30|km|mi}} and sociological differences between each club's supporters, a fierce rivalry developed. The North Derby is underpinned by social and economic differences, since the city of Lens is known as a working-class and industrial mining city whereas Lille as a middle-class, modern, internationally oriented cultural metropolis.<ref>{{cite web |language=fr |url=https://actu.fr/hauts-de-france/lens_62498/derby-du-nord-d-ou-vient-vraiment-cette-rivalite-historique-entre-lille-et-lens_54346363.html |title=Derby du nord.
