Tsirang District is one of the 20 dzongkhags (districts) of Bhutan. It is located in the South-western part of Bhutan on the Wangdue-Gelephu highway.
Tsirang is noted for its gentle slopes and mild climates. The dzongkhag is also noted for its rich biodiversity; however, it is one of the few dzongkhags without a protected area. One of Bhutan's longest rivers, the Punatsang Chhu or Sankosh river flows through the district. It is the main districts where the Lhotshampa (Nepali-speaking Bhutanese) reside.
