Alpamayo (possibly from Quechua allpa earth, mayu river, "earth river") or Shuyturaju (possibly from Ancash Quechua huytu, shuytu oblong, slim and long, Quechua rahu snow, ice, mountain covered in snow) is one of the most conspicuous peaks in the Cordillera Blanca of the Peruvian Andes. Alpamayo Creek originates northwest of it.

The Alpamayo lies next to the slightly higher Quitaraju.

In July 1966, the German magazine "Alpinismus", published a photo of Alpamayo taken by American photographer Leigh Ortenburger accompanied by an article on a survey among mountaineering experts, who chose Alpamayo as "The Most Beautiful Mountain in the World".
