Cerro Huemul, Mountain summit in Los Glaciares National Park, Argentina

Cerro Huemul is a glaciated mountain of the Andes in Patagonia, rising to 2,677 m on the eastern edge of the Southern Patagonian Ice Field, west of Lake Viedma and north of the glacier of the same name, in the area disputed between Chile and Argentina. Its western side lies in Chile's Bernardo O'Higgins National Park and its Argentine side in Los Glaciares National Park.

After the 1881 treaty between Argentina and Chile, the boundary in this sector was fixed in 1898 by the surveyors Francisco Pascasio Moreno (Argentina) and Diego Barros Arana (Chile), who declared Huemul a border landmark. They agreed on the line between Monte Fitz Roy and Cerro Stokes, unlike other sectors later submitted to the 1902 arbitration. The 1998 agreement between both countries defined the course of the limit from Fitz Roy toward Cerro Daudet, leaving the Fitz Roy–Murallón stretch pending.

The name Huemul refers to the South Andean deer of Patagonia, and the peak shares it with the neighbouring glacier and the Huemul Pass nearby. In 1898 the border experts Francisco Pascasio Moreno of Argentina and Diego Barros Arana of Chile fixed the frontier along the Fitz Roy, Torre, Huemul, Campana, Agassiz, Heim, Mayo and Stokes summits, and Chile still cites the mountain as a border landmark.

Cerro Huemul lies on the disputed Chile–Argentina boundary at the eastern edge of the Southern Patagonian Ice Field, west of Lake Viedma. Access is by a circuit from the Argentine town of El Chaltén, with the Huemul and del Viento passes nearby. The peak rises to 2,677 m and is heavily glaciated, so crampons and glacier travel experience are needed.

Cerro Huemul was declared a border landmark by the 1898 boundary experts Francisco Pascasio Moreno of Argentina and Diego Barros Arana of Chile. Unlike other stretches, they agreed on the line between Monte Fitz Roy and Cerro Stokes without dispute, so this sector escaped the 1902 arbitration. The 1998 agreement between the two countries fixed the boundary from Fitz Roy toward Cerro Daudet, leaving the Fitz Roy–Murallón section pending.
