Orangutans are great apes native to the rainforests of Indonesia and Malaysia. They are now found only in parts of Borneo and Sumatra, but during the Pleistocene they ranged throughout Southeast Asia and South China. Classified in the genus Pongo, orangutans were originally considered to be one species. From 1996, they were divided into two species: the Bornean orangutan and the Sumatran orangutan. A third species, the Tapanuli orangutan, was identified definitively in 2017. The orangutans are the only surviving species of the subfamily Ponginae, which diverged genetically from the other hominids between 19.3 and 15.7 million years ago.

Gunung Leuser National Park is a national park covering 7,927 km2 in northern Sumatra, Indonesia, straddling the border of North Sumatra and Aceh provinces, a fourth portion and three-fourths portion, respectively. The national park, settled in the Barisan mountain range, is named after Mount Leuser (3,119 m), and protects a wide range of ecosystems. An orangutan sanctuary at Bukit Lawang is located within the park. Together with Bukit Barisan Selatan and Kerinci Seblat National Parks, it forms a World Heritage Site, the Tropical Rainforest Heritage of Sumatra.
The Sumatran orangutan is one of the three species of orangutans. Critically Endangered, and found only in the north of the Indonesian island of Sumatra, it is rarer than the Bornean orangutan but more common than the recently identified Tapanuli orangutan, also found in Sumatra. Its common name is based on two separate local words, "orang" and "hutan" ("forest"), derived from Malay, and translates as 'person of the forest'.
The Bornean orangutan is a species of orangutan endemic to the island of Borneo. Together with the Sumatran orangutan and Tapanuli orangutan, it belongs to the only genus of great apes native to Asia. Like the other great apes, orangutans are highly intelligent, displaying tool use and distinct cultural patterns in the wild. Orangutans share approximately 97% of their DNA with humans. Also called mias by the local population, the Bornean orangutan is a critically endangered species, with deforestation, palm oil plantations, and hunting posing a serious threat to its continued existence.
The Borneo Orangutan Survival (BOS) Foundation is an Indonesian non-profit non-governmental organization founded by Dr. Willie Smits in 1991 and dedicated to the conservation of the endangered Bornean orangutan and its habitat through the involvement of local people.
