The Collasuyo Archaeological Research Institute (CARI) operates in partnership with the Institute for Field Research, a 501c3 non-profit organization. CARI-Peru is registered in Peru as an NGO that provides logistical support to researchers engaged in the archaeological and anthropological study of Andean culture and prehistory in the Lake Titicaca Basin, Puno, Peru.

CARI was originally established in 1999 under the name Programa Collasuyo by faculty of University of California Los Angeles, UC Santa Barbara, and the Universidad Nacional del Altiplano, Puno, Peru. It has operated continuously since that date, hosting academic researchers of the highest caliber from institutions in North and South America.

Over the last two decades, the majority of cutting-edge archaeological and ethnographic research in the northern and western Lake Titicaca Basin has been conducted through this research facility.
