Jigme Singye Wangchuck National Park, National park in Sarpang District, Bhutan.

Jigme Singye Wangchuck National Park is a large protected area covering central Bhutan with forests at different elevations. Four administrative ranges oversee different sections of the park, each managing distinct ecosystems and landscape types.

The park was created in 1995 as a protected area, receiving its current name at that time. This established formal protection for one of Bhutan's important forest regions.

The Nabji Lhakhang in the remote Nabji Park Range is among the park's most important historic sites. About 5,000 to 6,000 people live inside the protected area, and the park runs community-based ecotourism projects with them, including the Nabji-Korphu trail and the Adha-Rukha community trail.

The park's head office sits at Tshangkha beside the national highway in Trongsa District, and four range offices (Taksha, Langthel, Tingtibi, Nabji) plus two deputy ranges at Chendebji and Athang serve visitors. Bhutan's main east-west and north-south highways run along the park border. The Nabji range covers the most remote terrain and holds the historic Nabji Lhakhang.

The park holds Bhutan's only old-growth Chir pine (Pinus roxburghii) forest, and with 391 bird species it has more than any other national park in the country. The white-bellied heron, an endangered species, is among them, and black-necked cranes use the park as wintering grounds. BirdLife International lists the area as an Important Bird Area.
