The Aron (pronounced as /fr/) is a 103.8km (64.5miles) long river in central France. It is a right tributary of the Loire, which it meets at Decize. It flows through the department of Nièvre.
The source of the Aron is in the commune of Crux-la-Ville, about 35km (22miles) north-east of Nevers. It flows in a southerly direction, through the towns of Châtillon-en-Bazois and Cercy-la-Tour, and empties into the Loire at Decize. For much of its length, from Châtillon-en-Bazois to Decize, the river flows parallel to the Canal du Nivernais.
Among its tributaries is the Alène.
