The Compagnie anonyme de Châtillon et Commentry was a French steelmaking company, formed as a limited company in 1862 from the Société Bouguéret, Martenot et Cie., a creation from the combination of several French iron makers in 1846. In 1898 the company merged with the Société métallurgique de Champigneulles et Neuves-Maisons to form the Société des forges de Châtillon-Commentry-Neuves-Maisons.
