Pinkuylluna or Pinkulluna (Quechua, Hispanicized spellings Pincuylluna, Pinculluna) is an archaeological site on a mountain of the same name in Peru located in the Cusco Region, Urubamba Province, Ollantaytambo District.
It is situated between the rivers Patakancha (Patacancha) and Willkanuta, northeast of the town Ollantaytambo.
The name "Pinkuylluna" derives from the Pinkuyllu, a type of flute found throughout the Andes. It is unknown if literal Pinkuyllu were played at the site, as the name may be a reference to the prominent local mountain winds.
