Betung Kerihun National Park (previously Bentuang Karimun) is a national park in the province of West Kalimantan on the island of Borneo, Indonesia. It is located inland, along the Malaysian border. The park was established in 1995, and has a total area of 8,000 km² (3,100 sq mi) or about 5.5 percent of West Kalimantan Province area. Together with the 2,000 km² (800 sq mi) Lanjak Entimau Wildlife Sanctuary in Malaysia, it has been proposed to form a World Heritage Site named the "Transborder Rainforest Heritage of Borneo".

Betung Kerihun National Park is hilly and mountainous, with altitudes ranging from 150 m (490 ft) to almost 1,800 m (5,910 ft). The topography is characterized by steep slopes, with more than half of the park area having slopes over 45%. The highest peaks are Mount Kerihun (1,790 m or 5,870 ft) and Mount Lawit (1,767 m or 5,800 ft). The park is located at the headwaters of the Kapuas River.

The park largely consists of two ecoregions, Borneo montane rain forests, which covers about 2/3 of the area, and Borneo lowland rain forests.

In the lowland forests the dominant emergent trees are dipterocarp species, which are replaced at higher altitude with oaks (Quercus and Lithocarpus ssp.) and chestnut trees (Castanopsis ssp.). At least 97 species of orchid and 49 species of palm have been identified in the Park.

The fauna of the park is rich, with 300 species of bird (25 endemic to Borneo), at least 162 fish species and at least 54 mammals. The park is home to endangered Bornean orangutan and seven other primate species: Müller's Bornean gibbon, white-fronted surili, maroon leaf monkey, southern pig-tailed macaque, crab-eating macaque, Sunda slow loris and Horsfield's tarsier.
