The Aiguille du Chardonnet (3,824 m) is a mountain in the Mont Blanc massif in Haute-Savoie, France. It lies between the Glacier du Tour [fr] and the Argentière Glacier. The border with Switzerland (elevation: 3,680 m at its nearest point) runs just east of the summit. The East or Forbes Arete provides a popular and classic mountaineering route to the summit.
The summit was first climbed on 20 September 1865, by a party comprising R Fowler, M Balmat and M Ducroz. The first winter ascent was made some time prior to 1914.
