Pic de Chamoissière, Mountain summit in Hautes-Alpes, France

Pic de Chamoissière is a mountain summit in the Hautes-Alpes region rising to 3,207 meters, with steep rocky slopes and multiple climbing routes through the French Alps. The ascent passes through varied terrain and rock formations that present different levels of climbing difficulty.

The first recorded ascent was on 20 July 1899, by Maximin Gaspard, Jeanne Kayser and Joseph Turc, who climbed the north face and north-west ridge. The south ridge followed on 28 June 1953 with A. Rannou and Jacques Piégeay. Later lines include the Cret gully (26 June 1991, X. Cret) and the east couloir of the signal, the Véronique route, on 26 November 2004 by Henri Bizot and Philippe André.

The name Chamoissière probably comes from a Celto-Ligurian word for summit, "calm"; older forms were Chamoussier and Chamossy. The peak is the highest point of a north-south ridge above the Alpe de Villar d'Arène, with the signal de Chamoissière (3,019 m) and the pic ouest de Chamoissière (3,095 m). The Romanche rises on its western flank and the col d'Arsine lies on its eastern side.

Climbing the summit requires experience with technical rock climbing, appropriate gear, and good physical fitness, along with attention to changing mountain weather. The warmer months offer the most stable conditions for attempting the ascent.

The summit is the highest point of a north-south ridge above the Alpe de Villar d'Arène, which also holds the Signal de Chamoissière at 3,019 m and the western Pic de Chamoissière at 3,095 m. The Brèche Gaspard separates it from the Pic du Dragon (3,188 m).
