Hauts-de-France is the northernmost region of France, created by the territorial reform of French regions in 2014, from a merger of Nord-Pas-de-Calais and Picardy. Its prefecture is Lille. The new region came into existence on 1 January 2016, after regional elections in December 2015. The Conseil d'État approved Hauts-de-France as the name of the region on 28 September 2016, effective the following 30 September.

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.
