Tanjung Puting National Park is a national park in Indonesia located in the southeast part of West Kotawaringin Regency in the Indonesian province of Central Kalimantan (Central Borneo). The nearest main town is the capital of the Regency, Pangkalan Bun. The park is famous for its orangutan conservation.
The park was set aside in the 1930s by the Dutch colonial government for the protection of the orangutans and proboscis monkey, and was designated as a UNESCO Biosphere Reserve in 1977 and a national park in 1982.
In addition to orangutans and proboscis monkeys, the park is also home to gibbons, macaques, clouded leopards, sun bears, wild boars, porcupines, and Sambar deer. The park also features many reptiles, including crocodiles, monitor lizards, and pythons, birds, including hornbills and kingfishers, and insects, such as the giant Bornean butterfly. The Pondok Ambung Tropical Forest Research Station was established in 2005 for the study of all wild species found in the Park.
