The Colmont (French pronunciation: [kɔlmɔ̃]) is a 50.4 km (31.3 mi) long river in western France located in the departments of Orne, Manche (Normandy) and Mayenne (Pays de la Loire). It is a tributary of the river Mayenne on the right side, and so is a sub-tributary of the Loire by Mayenne and Maine.1 It flows into the Mayenne near Saint-Loup-du-Gast. Its longest tributary is the Ourde (11 km).1 The largest town on the Colmont is Gorron.
