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.

The langues d'oïl are a dialect continuum that includes standard French and its closest autochthonous relatives historically spoken in the northern half of France, southern Belgium, and the Channel Islands. They belong to the larger category of Gallo-Romance languages, which also include the historical languages of east-central France and western Switzerland, southern France, portions of northern Italy, the Val d'Aran in Spain, and under certain acceptations those of Catalonia.
