Courcelles (French pronunciation: [kuʁsɛl] ⓘ; Walloon: Courcele) is a municipality of Wallonia located in the province of Hainaut, Belgium.

The municipality consists of the following districts: Courcelles, Gouy-lez-Piéton, Souvret, and Trazegnies.

In 1944, the town was the site of the Courcelles Massacre of 20 civilians by Belgian collaborators.

In 1853, a company, called Société Anonyme des Charbonnages du Nord de Charleroi, was formed to bring together the various concessions located in Courcelles.

The shafts were closed one by one and currently, no extraction shaft is in operation on the territory of Courcelles, but we can still see a lot of spoil tips which are now nice places for walking.
