Nañuhuaico (possibly from Quechua ñañu thin (cylindrical objects), slim, wayq'u brook,[2] "thin brook") is a 4,932-metre-high (16,181 ft) mountain in the Vilcabamba mountain range in the Andes of Peru.

It is located in the Cusco Region, La Convención Province, Vilcabamba District.

[1][3] Nañuhuaico (erroneously spelled Nunahuayco) is also the name of a stream which originates north of the mountain.

It is a left affluent of the Hatun Wayq'u ("big brook") in the north whose waters flow to the Apurímac River as a right tributary.
