Pacopampa (Quechua: paqu pampa) is an archaeological site located in the northern highlands of Peru, in the department of Cajamarca.

The land where the reservoir extends belongs to the National University of San Marcos, which through its Rural Andean History Seminar cares permanently for the monument.

Anxious to protect it, in 1970 succeeded Dr. Emilio Choy made a donation to the University of San Marcos so that it could acquire the land so that the excavations would start.

In 2009 a team of archaeologists of the Pacopampa Archaeological Project, directed by Yuji Seki, announced the discovery of the tomb of a woman, presumably a person of great power in the area, from around 900 BC or so.

She had an artificially deformed skull and she was buried with rich grave goods composed by earmuffs, gold earrings, ceramic pots and seashell necklaces.
