Monte Clapier (French: Mont Clapier) is a mountain in the Maritime Alps, on the boundary between the province of Cuneo (Piedmont, northern Italy) and the French region of Provence-Alpes-Côte-d'Azur.

Monte Clapier is home to the southernmost glacier in the Alps, located on the Italian side at some 40 km from the sea.

Furthermore, it is the southernmost mountain in the Alps exceeding 3000 meters in height.

It may be climbed from the Refuge Nice in around two-and-a-half to three hours,[3] initially northward along a narrow path towards the Lacs de Mont Clapier, then eastward along a cairned route (no path visible) across rough, bouldered ground.

The view is extensive stretching from the Mediterranean to the south to the high Alps to the northeast.
