: Dente del Gigante, "giant's tooth") (4,013 m) is a mountain in the Mont Blanc massif in France and Italy.

The Dent du Géant remained unclimbed during the golden age of alpinism, and was a much-coveted peak in the 1870s, repelling many parties who attempted it mostly from the Rochefort ridge.

'[2] The mountain has two summits, 27 metres (88 ft) apart and separated by a small col (an 'extremely awkward notch' according to W. W. Graham):[3] This ascent marked the end of the so-called silver age of alpinism.

On 28 July 1935 the Austrian climbers Herbert Burggasser and Rudi Leitz first ascended the vertical-to-overhanging 160 m-high south face.

[5] During a heat wave in the summer of 2019, a glaciological rarity in the form of a previously unseen lake emerged at the foot of the Dent du Géant, the Aiguilles Marbrées and the Col de Rochefort at an altitude of about 3400 meters, that was considered as evidence for the effects of global warming on the glaciers in the Alps.
