The province derives from the French Revolutionary Jemmape department, formed in 1795 from part of the medieval County of Hainaut, Tournai and the Tournaisis, a part of the county of Namur (Charleroi) and of the Prince-Bishopric of Liège (Thuin). (A large part of the historical county is now within France and sometimes referred to as French Hainaut.)
The patron saint of the province Hainaut is Saint Waltrude.
