The Aiguille Blanche de Peuterey (4,112 m) is a mountain of the Mont Blanc massif in Italy.

In July 1882, Francis Maitland Balfour, a young English professor, lost his life whilst attempting the as-yet-unclimbed summit of the Aiguille Blanche along with his guide Johann Petrus (an uncle of Joseph Knubel).

[3] Together with its neighbour – the Aiguille Noire de Peuterey (3,773 m) – the Aiguille Blanche forms part of the Peuterey ridge that leads, via the summit of the Grand Pilier d'Angle, to the summit of Mont Blanc.

[1] The main ridge itself was first climbed via a couloir on the Brenva face by Paul Güssfeldt with Emile Rey, Christian Klucker and César Ollier on 15–19 August 1893 (the second ascent was a week later by Klucker and John Percy Farrar).

The first ascent of the complete ridge including the Aiguille Noire de Peuterey (the Intégrale) was on 28–31 July 1934 by Adolf Göttner, Ludwig Schmaderer and Ferdinand Krobath.
