Aragon (French pronunciation: [aʁaɡɔ̃] ⓘ; Occitan: Argon) is a commune in the Aude department in the Occitanie region of southern France.

The Ruisseau de Trapel flows from the north-west passing north of the village and gathering tributaries as it continues south-east to join the Canal du Midi south of Les Pradels.

The name could come from the Kingdom of Aragon and dates from the 11th century but some propose Celtic or Greco-Celtic origins meaning a place near a battle or near the wilderness.

Other Places: Champ du Saule, Clapier d'Amen, Clapier Rouge, l'Espinal, la Croix du Carabier, Larjale, le Malrégas, les Précieuses, Mont Feste, Mourrel de la Crose, Mourrel Redon, Pechicous, Plateau d'Aragon, and Pratjon.

The village experienced a period of prosperity in the late 18th century when looms for supplying the clothiers at Carcassonne brought additional revenue to the community.
