Mount Fitz Roy is a mountain in Patagonia, on the border between Argentina and Chile. It is located in the Southern Patagonian Ice Field, near El Chaltén village and Viedma Lake. It was first climbed in 1952 by French alpinists Lionel Terray and Guido Magnone.

Argentina and Chile have agreed that their international border detours eastwards to pass over the main summit, but a large part of the border to the south of the summit, as far as Cerro Murallón, remains undefined. 

The mountain is the symbol of the Argentine Santa Cruz Province, which includes its representation on its coat of arms.
