Mauron (French pronunciation: [moʁɔ̃]; Breton: Maoron) is a commune in the Morbihan department and Brittany region of north-western France.

Mauron's location make it a crossroads on the routes connecting Dinan to Vannes and Quimper to Rennes.

Aerial archaeology has revealed the existence of a large number of Gaulish farms, attesting to the agricultural wealth of the territory, which is traversed by the Roman road leading from Quimper to Rennes.

On 14 August 1352 six hundred French Bretons (who supported King John II of France, the protector of Charles of Blois) under the leadership of the marshal of Offemont fought Anglo-Breton troops (supporting the Montfort side) which was led by Gaultier de Genteley (or Venteley, or Benteley).

The king's troops lost the battle, and many corpses were left on the field of battle, including those of the marshal of Offemont, the count of Marche, the lords of Bricquebec and Beauvais, Alain VII (11th viscount Rohan), Tinténiac, and a significant number of knights (around 140).
