Wilcahuaín,[1][2][3] Willcahuaín,[4] or Huilcahuaín[5][6] is an archaeological site in Peru.

[4] It is located near the village of Paria, 7 km northwest of the city of Huaraz, Ancash; at an elevation of 3,400 m (11,200 ft).

[4] Wilcahuaín is regarded as one of the most important archaeological sites of the Wari culture.

The last half of the route is on very rough road.

Wilcahuaín possibly comes from Quechua willka grandchild; great-grandson; minor god; holy; sacred or Anadenanthera colubrina (a tree),[7][8][9] and Ancash Quechua wayi house.
