Clermont-l'Hérault (French pronunciation: [klɛʁmɔ̃ leʁo]; Occitan: Clarmont d'Erau) is a commune in the Hérault department in southern France.

Chief town of the Canton, Clermont-l'Hérault is located about 40 km west of Montpellier, halfway between the Mediterranean Sea to the south and the Cévennes National Park to the north.

The site of Clermont-l'Hérault has been inhabited since Protohistory: during the Iron Age (6th century BC), Clermont constitutes one of the main Oppida of the Celtic Mediterranean.

The manufacture of sheets was established at nearby Villeneuvette, or rather relaunched in 1667 by Colbert to develop the cloth industry in France, taking advantage of the waters of the Dourbie.

The town is built on the slope of a hill ("Pioch Castel") which is crowned by an ancient castle (Château des Guilhem) and skirted by the Rhonel, a tributary of the Lergue.
