Uncontacted Tribes of the Amazon

The last peoples on Earth living outside recorded contact — hidden deep in the Amazon rainforest

Active — Uncontacted tribes in the Amazon live mostly in remote parts of Brazil and Peru, with the largest concentration in Brazil's Vale do Javari on the Brazil-Peru border. Their exact locations are intentionally kept secret to protect them from contact, disease and encroachment.

Deep in the Amazon rainforest live the last peoples on Earth who remain largely uncontacted by the outside world. These uncontacted, or isolated, tribes primarily inhabit remote regions of Brazil and Peru, with smaller groups in Bolivia, Colombia, Ecuador and Venezuela.

The largest concentration is in Brazil's Vale do Javari (Javari Valley), on the Brazil-Peru border, an area of about 85,000 square kilometers where more than a dozen uncontacted groups live. Other significant populations exist in Peru's Madre de Dios region. In total, researchers estimate there may be anywhere from 70 to over 100 uncontacted groups in Brazil alone.

These tribes are extremely vulnerable. When uncontacted peoples come into contact with the outside world, they often fall victim to diseases to which they have no immunity — which has led to entire communities being wiped out by a single encounter. For this reason, the exact locations of the tribes are deliberately kept secret, and organizations and governments work to protect the groups from intrusion.
