Caux (French pronunciation: [ko]; Occitan: Cauç) is a commune in the Hérault department in southern France.

Caux is a Circulade village located near Pézenas

The origin of the name "Caux" has two possible explanations:

1. It can come from Occitan "caus" which means "lime". This is possible because limestone is very present on the territory, lime kilns are numerous; we find their remains at Sallèles and Maro Road.
2. The name can come from an expression of pre-Indo-European origin: "cal-so", that is to say rock, shelter. Indeed, on its base at 103 meters above sea level, Caux dominates the surroundings.
