Cerro Campana[1][2][3][4] is a glaciated mountain in the Andes mountain range in Patagonia, located on the eastern edge of the Southern Patagonian Ice Field, west of Lake Viedma, and south of the glacier of the same name within the disputed area between Chile and Argentina.

For Argentina, the mountain has been part of Los Glaciares National Park since 1937, in the Lago Argentino Department of Santa Cruz Province, which was declared a UNESCO World Heritage Site in 1981.

For Chile, its western side has been part of Bernardo O'Higgins National Park since 1969, in the Natales commune of Última Esperanza Province in the Magallanes and Chilean Antarctic Region.

The boundary was defined by the following mountain landmarks and their natural continuity: Mount Fitz Roy, Torre, Huemul, Campana, Agassiz, Heim, Mayo, and Stokes (nowadays Cervantes).

[4] In 1998, the "Agreement between the Republic of Chile and the Republic of Argentina to determine the boundary line from Mount Fitz Roy to Cerro Daudet" was signed, defining section A and a small part of section B, with the area between Fitz Roy and the Murallón still pending.
