The Vidourle (Vidorle in occitan) is a river in southern France, flowing into the Mediterranean Sea in Le Grau-du-Roi. Its source is in the Cévennes mountains, northwest of Saint-Hippolyte-du-Fort, at Saint-Roman-de-Codières. It flows generally southeast. At Gallargues-le-Montueux, it was crossed by the old Roman road Via Domitia with the now ruined Roman bridge Pont Ambroix.
