Thimphu District (Dzongkha: ཐིམ་ཕུ་རྫོང་ཁག་; Wylie: Thim-phu rdzong-khag) is a dzongkhag (district) of Bhutan. Thimphu is also the capital of Bhutan and the largest city in the whole kingdom.
The dominant language throughout the district is Dzongkha; however, within the capital nearly every language of Bhutan may be encountered.[2]
Thimphu District is divided into eight gewogs and one town (Thimphu):[3]
Lingzhi, Soe and Naro Gewogs belong to the Lingzhi Dungkhag subdistrict, the only subdistrict within Thimphu District. The remaining gewogs do not belong to any subdistrict.[4]
Thimphu is the capital of Bhutan and Thimphu district.
The northern half of Thimphu District (the gewogs of Kawang, Lingzhi, Naro and Soe – corresponding roughly to Lingzhi Dungkhag) is subject to environmental protection, falling within Jigme Dorji National Park.[5]
