Ntangki National Park, National park in Nagaland, India

Ntangki National Park is a protected forest area in Nagaland featuring dense evergreen forests mixed with deciduous trees, bamboo thickets, and numerous streams running through the terrain. This landscape creates habitats for many different animals and plants.

Ntangki Reserved Forest was created in 1923 at about 181 km2 and enlarged by 20.7 km2 in 1927. In April 1975 the Nagaland government declared it Ntangki Wildlife Sanctuary, 202.02 km2. In March 1993 it became Ntangki National Park.

The name "Ntangki" comes from the Zeme dialect of the Zeliangrong Nagas, the indigenous people native to the area around the park in Peren District. The park lies in their homeland, and the name itself is the clearest trace of that link a visitor encounters.

Ntangki National Park lies in Peren District, Nagaland. Permits must be obtained before entering, and visitors can stay in designated forest rest-houses or in hotels and lodges nearby. The park is open throughout the year, but October to April is the best time to visit.

In 2022, Asian forest tortoises were reintroduced here by the Turtle Survival Alliance and Wildlife Conservation Society India, after the species had disappeared from the park. The release took place in a reserve that began as a 181 km2 forest in 1923.
