The Collasuyo Archaeological Research Institute (CARI) 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 is registered in the US as a nonprofit 501(c)(3) organization and in Peru as an NGO.

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 leading academic researchers 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.
