The Hérault (French pronunciation: [eʁo] ⓘ; Occitan: Erau) is a river in southern France.

[1] Its source is on the slopes of Mont Aigoual in the Cévennes mountains.

The name is sometimes considered Pre-Celtic although the element Ara- suggests a Celtic root.

[4][5] At the upper end of the section of the Hérault used by the Canal du Midi, the Prades Lock provides access to the Canal du Midi to the east.
