Le Quesnoy is a commune and small town in the east of the Nord department of northern France. It was part of the historical province of French Hainaut. It is known for its fortifications, dating from the 16th, 17th and 18th centuries. It had a significant shoemaking industry 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.
