Pointe Lachenal, Granite summit in Savoie, France.

Pointe Lachenal is a 3,613-metre mountain of snow and rock in the Mont Blanc massif, standing above the Glacier du Géant, beneath the east face of Mont Blanc du Tacul and opposite the Aiguille du Midi. Its south-east side is a large wall of clean, steep granite, and the ridge carries four summits.

The summit is named after Louis Lachenal (1921–1955), the French alpinist and guide who reached the top of Annapurna in 1950 with Maurice Herzog's expedition. Lachenal died on 27 November 1955 when he fell into a crevasse on the Glacier du Géant below this mountain. A peak in the Annapurna Himal, Lachenal Peak (7,140 m), also bears his name.

The summit and its ridge carry the name of Louis Lachenal, the Chamonix guide who reached the top of Annapurna in 1950 and died on 27 November 1955 in a fall on the Glacier du Géant below this mountain. Climbers on the north-face route of Mont Blanc pass over the crest, and the same name was given to Lachenal Peak (7,140 m) in the Annapurna Himal.

The usual approach is via the Aiguille du Midi cable car from Chamonix, then a descent onto the Glacier du Géant; the summit is reached over the crest, below the east face of Mont Blanc du Tacul. The terrain mixes snow and rock, so rope, crampons and glacier travel experience are needed.

Louis Lachenal, after whom the peak is named, died on 27 November 1955 in a fall on the Glacier du Géant below this mountain; he had reached the summit of Annapurna in 1950. A peak in the Annapurna Himal, Lachenal Peak at 7,140 m, also bears his name.
