大乔拉斯峰（法语：Grandes Jorasses）一译大若拉斯山，为法国和意大利交界处格雷晏阿尔卑斯山脉中的一座山峰，海拔4208米。大乔拉斯峰的北坡非常险峻，与马特洪峰、艾格峰并称为欧洲三大北壁。为著名的攀岩胜地。

The Grandes Jorasses (4,208 m; 13,806 ft) is a mountain in the Mont Blanc massif, on the boundary between Haute-Savoie in France and Aosta Valley in Italy.

The first ascent of the highest peak of the mountain (Pointe Walker) was by Horace Walker with guides Melchior Anderegg, Johann Jaun and Julien Grange on 30 June 1868. The second-highest peak on the mountain (Pointe Whymper, 4,184 m; 13,727 ft) was first climbed by Edward Whymper, Christian Almer, Michel Croz and Franz Biner on June 24, 1865, using what has become the normal route of ascent and the one followed by Walker's party in 1868.
