Uncontacted people, also referred to as isolated people or lost tribes, are communities who live, or have lived, either by choice (people living in voluntary isolation) or by circumstance, without significant contact with globalised civilization. Few people have remained totally uncontacted by global civilization. Indigenous rights activists call for such groups to be left alone, stating that it will interfere with their right to self-determination. Most uncontacted communities are located in densely forested areas in South America and New Guinea. Knowledge of the existence of these groups comes mostly from infrequent and sometimes violent encounters with neighbouring tribes, and from aerial footage. Isolated tribes may lack immunity to common diseases, which can kill a large percentage of their people after contact.
Uncontacted tribes are a source of fascination in developed society, and the idea of tour operators offering extreme adventure tours to specifically search out uncontacted people has become controversial. A BBC Four documentary in 2006 documented a controversial American tour operator who specializes in escorted tours to "discover" uncontacted people in West Papua, similar to the BBC's own adventure in Papua New Guinea to make their 1971 documentary A Blank on the Map in which the first contact in over a decade was made with the Biami people.
Andaman Islands, India 
Sentinelese people 
The Sentinelese continue to actively and violently reject contact. They live on North Sentinel Island, a small and remote island which lies to the west of the southern part of South Andaman Island. They are thought to number around 250 (median estimate). Based on helicopter surveys of the island, the 2004 Indian Ocean tsunami does not appear to have affected the Sentinelese adversely.
It is estimated that they have lived on their island for 60,000 years. Their language is markedly different from even other languages on the Andamans, which suggests that they have remained uncontacted for thousands of years. They are thus considered the most isolated people in the world, and they are likely to remain so.
Another Andamanese tribe, the Jarawa, live on the main islands. They rejected all contact, but following the completion of a trunk road traversing their territory in 1997, some have begun emerging from the forest into the open. They are thought to number 300 people.
The Ruc people, when first encountered by North Vietnamese soldiers during the Vietnam War, were hunting-gathering tribes, dwelling in caves of eastern Quang Binh province. Since then, the government has made many attempts to relocate them.
In 1984, a group of Pintupi people who were living a traditional hunter-gatherer life were tracked down in the Gibson Desert in Western Australia. For the first time, they encountered people from European-Australian society. They are believed to have been the last uncontacted tribe in Australia.
New Guinea 
Large areas of New Guinea are unexplored by scientists and anthropologists due to extensive forestation and mountainous terrain. Indigenous tribes in Papua New Guinea are generally contacted in the sense that local authorities know they are there, but many remain pre-literate and out of reach of modern medicine and technology, and at the national or international level, the names of tribes and information about them may be extremely hard to obtain.
The Indonesian provinces of Papua and West Papua on the island of New Guinea are home to an estimated 44 uncontacted tribal groups. Isolated tribes have been reported also in the eastern Indonesian islands.
North America 
United States 
Ishi, a Yahi, is believed to be the last Native American in Northern California to have lived most of his life completely outside the European American culture. In the year 1911, he emerged from the wild near Oroville, California, leaving his ancestral homeland in the foothills near Lassen Peak.
South America 
As of 2006, the presence of five uncontacted groups was confirmed in Bolivia; three more uncontacted groups are believed to exist. The groups whose presence has been confirmed are: the Ayoreo in Kaa-Iya National Park, the Mbya-Yuqui in the Yuqui Reservation and Rio Usurinta (most of the Yuqui are now contacted; only a few families remain uncontacted), the Yurakare in Santa Cruz and Beni, the Pacahuara in the Chacobo reservation, and a group of Araona in the Araona Reservation, and the Toromona in Madidi National Park. The presence of other groups, such as the Nahua in Madidi National Park has yet to be confirmed.
|Sinabo/Kapuibo (Nahua)||Under 200||Between the lower Beni and the lower Yata||
|Toromona||Unknown||Eastern bank of the Manurini River, Madidi National Park|
|Yanaigua||100–200||Between the Rio Grande and Upper San Miguel|
|Yuqui||100||Between Upper Ichilo and Upper Yapacani||
On January 18, 2007, FUNAI reported that it had confirmed the presence of 67 uncontacted tribes in Brazil, up from 40 in 2005. With this reported increase, Brazil has surpassed the island of New Guinea (divided between Indonesia and Papua New Guinea) as the region having the highest number of uncontacted tribes.

Of the known uncontacted peoples of Brazil, according to the above, 16 live in the Brazilian state of Amazonas, 7 in Rondônia, 8 in Pará, 2 in Acre, 3 in Mato Grosso, and one each in Amapá, Maranhão, Roraima, Tocantins, Goiás and Minas Gerais. Keep in mind some migrate between state lines.
Due to ongoing paramilitary conflict, Colombia is a country that offers little protection for isolated groups. Carabayo-Aroje is the one such group, living in the Parque Nacional del Rio Pure. It is not known whether any Yari (another tribe believed to be uncontacted) survives now. Nukaak Maku were contacted in 2003 and 65% of the tribal members died of disease. Around two or three dozen Nukaak still remain isolated.
|Carabayo||150||Amazonas – Source of the Purué River, north of the Putumayo River|

It is not known whether any Tagaeri survives now in Yasuni National Park. In the 1990s when a member of Tagaeri was contacted by a lone Huaorani hunter, he told him that Tagaeri numbers only a handful of members and are in danger of being wiped out by their hostile neighbours – the Taromenane. Since then there have been no more peaceful contacts. The Tagaeri hunter also mentioned about another group, the Oñamenane who numbered five or six individuals and there was one more tribe – the Huiñatare. In 2003 about 30 Taromenane were massacred by the Huaorani in retaliation for the killing of a Huaorani hunter. In the same year 14 Tagaeri were killed by loggers. In April 2006 a logger was speared to death by the Taromenane (in 2005 another one was also killed by the same tribe, whose body was later found embedded with 30 spears and his face unrecognizable). In the same month a further 30 Taromenane and 10 loggers were killed in conflicts according to leader Iki Ima Omene (of Huaorani). In Jan 2007 the president of Ecuador declared the Southern part of Yasuni a forbidden zone (7,580 square kilometers) in order to protect the uncontacted people. At the same time CONAIE reported that there are a total of 150–300 Taromenane (divided into two sub-tribes) and 20–30 Tagaeri surviving uncontacted there. The Oñamenane and Huiñatare are extinct.

|Wayãpi||100||Between the Eureupoucine and the Upper Camopi||
|Wapishana||100||Between the sources of the Essequibo River and the Tacutu River; Serra Acarai||

There remain perhaps as many as 300 Totobiegosode who have not been contacted; they belong to the Ayoreo ethnicity, which numbers around 2,000. In the 1990s the main group attempting to contact them was New Tribes Mission. In 1979 and 1986, the New Tribes Mission was accused of assisting in the forcible contact of nomadic Ayoreo Indians, whose unsuccessful attempts to remain in the forest led to several native deaths. Others died soon after being brought out of the forest. The incident forced some Ayoreo to flee to Bolivia. Currently the main threat to these peoples are ranchers, who illegally encroach on their lands. In 2004 a group of 17 Ayoreo-Totobiegosode previously uncontacted made contact with the outside world and decided to settle down (five men, seven women and five children, according to Survival). It was not known whether there were any more isolated Ayoreo left in the jungle. In the first week of September 2007, another uncontacted band of Ayoreo-Totobiegosode were spotted by loggers in the Western Chaco. Ayoreo are believed to be the last uncontacted Indians south of the Amazon basin. In 2008, a Paraguayan ruling blocked a Brazilian company from clearing Totobiegosode to make room for cattle ranches, although the forest is still being cleared illegally.
There are now five reserves in the Peruvian Amazon meant to protect the lands and rights of isolated peoples. Most of the reserves are currently entered by illegal loggers and petroleum companies with legal concessions to work in those lands, although their activities jeopardize the lives of the isolated populations.
After Brazil (67 uncontacted groups confirmed) and New Guinea (Papua New Guinea and Iriyan Jaya), Peru has the largest number of uncontacted tribes in the world (15). Some of the groups in Peru are in danger of extermination by loggers and oil development. As of 2006, the locations where uncontacted groups are confirmed to be living are as follows:
- Amarakaeri Communal Reserve: Groups are Yora and other unidentified Panoan tribes.
- Zona Reservada Biabo Cordillera Azul: Cacatibo.
- Parque Nacional del Manu: Mashco-Piro, uncontacted bands of Matsiguenga, tribes belonging to Yura family and unidentified tribes.
- Reserva Communal Asháninka, Reserva Communal Matsiguenga and Parque Nacional Otishi: uncontacted bands of Ashaninka.
- Parque Nacional Alto Purús and Reserva Communal Purús: Yaminahua, Chitonahua, Curajeño and Mashco-Piro-Iñapari.
- Reserva Territorial del Estado: Kungapakori, Nahua, Matsiguenga, Nanti, Krineri and other unidentified tribes.
- Reserva Territorial del Murunahua y Chitonahua: Murunahua, Chitonahua.
- Reserva Territorial del Isconahua: Isconahua.
- Reserva Territorial del Mashco-Piro: Various tribes belonging to Mashco-Piro such as Mascho-Piro-Iñapari.
- Reservas territoriales del Cacataibo: Cacataibo.
|Morunahua||150||This group is probably related to the group that used to be called Papavo in Brazil.|
|Parquenahua||200||Pano. They live in the Manu national park.|
|Akulio||50||Watershed between Suriname and Brazil. Between the sources of the Itani and the Jari||
