Le Quesnoy is a commune and small town in the east of the Nord department of northern France; accordingly its historic province is French Hainaut. It had a keynote industry in shoemaking before the late 1940s, followed by a chemical factory and dairy, giving way to its weekly market, tourism, local commuting to elsewhere such as Valenciennes and local shops.
Le Quesnoy's inhabitants are known as Quercitains.
