The Canon de 8 de Vallière was a type of cannon designed by the French officer Jean-Florent de Vallière (1667–1759), Director-General of the Battalions and Schools of the Artillery. The 8-pounder gun was part of the Vallière system which was established in 1732 with the intention of reducing the variety of cannons to five calibers and the types of mortars to three calibers, of standardizing their production, and of manufacturing all new artillery pieces in France.
