Hainaut, historically also known as Heynault in English, is a province of Wallonia and Belgium.

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.
