Le Quesnoy is a commune in the Nord department in northern France.

Le Quesnoy's inhabitants are known as Quercitains.

The town of Le Quesnoy has somehow missed much of the Industrial Revolution. Unlike the neighboring towns of Valenciennes or Maubeuge, iron/steel works did not take hold. The lack of wealth underground and of a major transportation route partly explains this. The authorities however took note of this weakness and proposed the Ecaillon canal from Sambre to Scheldt; considered but abandoned because of low water yield in the forest of Mormal.

There is a craft, however, firmly maintained until 1945 when a hundred shoemakers were still identifiable. Shoemakers worked at home for a local company located in rue du Petit Valenciennes(now Désiré Tanis) in a kind of cottage industry. A glassmaking factory installed near the railway track to the site of the former Intermarché collapsed after the World War I. In the Bellevue district, the remains of a factory attest to the presence of a former pottery factory.
