Ahu Vinapu is an archaeological site on Rapa Nui (Easter Island) in Chilean Polynesia.
The ceremonial center of Vinapu includes one of the larger ahu on Rapa Nui. The ahu exhibits extraordinary stonemasonry consisting of large, carefully fitted slabs of basalt. The American archaeologist, William Mulloy investigated the site in 1958.
The stone wall faces towards sunrise at Winter Solstice.
Vinapu is part of the Rapa Nui National Park, which UNESCO has declared a World Heritage Site.
According to the thesis of Jean Hervé Daude: Île de Pâques - L'empreinte des Incas, ahu Vinapu have been built by the Inca Tupac Yupanqui during his expedition to the Pacific in 1465. A Chullpas Sillustani in the Andes has been built under the reign of the Inca Tupac Yupanqui in the same way that the ahu Vinapu.
