Aiguille de Tré la Tête, Alpine summit in Mont Blanc massif, France and Italy.

Aiguille de Tré la Tête is an alpine peak in the Mont Blanc massif reaching 3,930 meters, with four distinct summits straddling the France-Italy border. The mountain displays rocky formations and ridge systems characteristic of high alpine terrain in this mountain range.

The first ascent of the eastern and southern summits was made on 12 July 1864 by Anthony Adams Reilly and Edward Whymper with guides Michel Croz, Michel Payot and Henri Charlet. The northern summit (Tête Blanche) followed on 23 July 1870 with Adolphus Warburton Moore, Horace Walker, Jakob Anderegg and Johann Jaun, and the central summit on 8 August 1878 with Martino Baretti and the Maquignaz and Sibille guides. The highest point, the central southeast pinnacle at 3,930 m, lies entirely in Italy.

The name Tré la Tête, roughly "beyond the head", is used for the whole chain that links the summits with the Dômes de Miage. The highest summit, the central southeast pinnacle at 3,930 m, lies entirely in Italian territory, while only the northwest pinnacle sits on the French border. The western slope falls within the Contamines-Montjoie Nature Reserve.

Experienced climbers access the summit via the ENE ridge route to Bivouac Rainetto with a PD+ technical difficulty rating on the alpine scale. The ascent requires solid rock and ice climbing skills along with prior alpine experience.

In September 2007 a hiker found the body of a mountaineer at about 2,500 m on the glacier, below a mountain trail. He was a 24-year-old who had vanished on 4 August 1954 with his 21-year-old brother and 16-year-old sister while returning from the Aiguille de la Lex Blanche (3,697 m); the other two bodies lay two kilometres above the foot of the glacier face.
