Aiguillette, Alpine peak in Hautes-Alpes, France and Piedmont, Italy.

Aiguillette is a 3,298 m peak on the main Alpine watershed between the Col de l'Agnel and the Monviso massif, on the France–Italy border. It is the highest point of the ridge between Monte Salza and Monviso. The summit is bifid, formed of two tops of equal height, and the mountain is built of Triassic–Jurassic calcschists with limestone beds and gneiss bands.

The summit lies on the main Alpine watershed between the Col de l'Agnello and the Monviso massif, on the border between Italy's Varaita Valley and the upper Guil valley in France. It is the highest point of the watershed between Monte Salza and the Monviso node. French IGN maps also label it L'Asti and give a height of 3287 m.

Local shepherds drive their flocks up to these alpine meadows during summer months as part of their traditional pastoral cycle. Both French and Italian communities have maintained this seasonal movement for generations.

The climb requires full alpine equipment and strong physical fitness, so only experienced mountaineers should attempt the ascent. Multiple marked routes offer different approaches, but all demand careful planning and preparation.

The summit is bifid: two separate tops of the same altitude, 3,298 m on Italian maps. French IGN maps label the mountain L'Asti and give 3,287 m, so the two national surveys differ by about eleven metres rather than placing the tops at different heights. The mountain is built of Triassic-Jurassic calcschists with limestone beds and gneiss bands, part of Gastaldi's greenstone complex.
