Val d'Hérens is an alpine valley in the Valais canton of Switzerland. It was formed by the Hérens glacier, which retreated at the end of the last ice age. It is now the valley of the Borgne river, a tributary of the Rhone (confluence above Sion)

It extends from the Rhône valley to a number of high mountains - Dent Blanche, Dent d'Hérens, Mont Collon, Mont Blanc de Cheilon. It is a popular start point for mountain expeditions.
