Mont Granier (1,933m) is a limestone mountain located between the départements of Savoie and Isère in France.

In the night of between January 8–9, 2016, a part of the northwest pillar crumbled towards Entremont-le-Vieux, where residents woke up at 5 in the morning.

The last debris were stopped by trees within 300 m of the closest houses, lying in the hamlets of Brancaz and Tencovaz.

On November 13, 1988, cavers Pierre Guichebaron and Marc Papet discovered an extension to the Balme à Collomb cave on the west side of the mountain at an altitude of 5,577 feet (1,700 meters) that contained the skeletons of over 1,000 cave bears that date between 24,000 and 45,000 years.

The current Granier massif is a remnant of a previously larger plateau reduced by erosion.
