Nord-Pas-de-Calais ; Picard: Nord-Pas-Calés); is a former administrative region of France. Since 1 January 2016, it has been part of the new region Hauts-de-France. It consisted of the departments of Nord and Pas-de-Calais. Nord-Pas-de-Calais borders the English Channel (west), the North Sea (northwest), Belgium and Picardy (south). Until the 17th century, the history of the North was largely in common with the history of Belgium, that of a land that “for almost a thousand years served as a battlefield for all of Europe.” The majority of the region was once part of the historical Southern Netherlands, but gradually became part of France between 1477 and 1678, particularly during the reign of king Louis XIV. The historical French provinces that preceded Nord-Pas-de-Calais are Artois, French Flanders, French Hainaut and (partially) Picardy. These provincial designations are still frequently used by the inhabitants. The former administrative region was created in 1956 under the name "Nord" and maintained that name until 1972 when "Pas-de-Calais" was added. This remained unchanged until its dissolution in 2016.

Picard is a langue d'oïl of the Romance language family spoken in the northernmost of France and parts of Hainaut province in Belgium. Administratively, this area is divided between the French Hauts-de-France region and the Belgian Wallonia along the border between both countries due to its traditional core being the districts of Tournai and Mons.
