The Barre des Écrins is a mountain in the French Alps with a peak elevation of 4,102 metres. It is the highest peak of the Massif des Écrins and the Dauphiné Alps and the most southerly alpine peak in Europe that is higher than 4,000 metres. It is the only 4,000-metre mountain in France that lies outside the Mont Blanc Massif. Before the annexation of Savoy in 1860 it was the highest mountain in France.
