Bumthang District (Dzongkha: བུམ་ཐང་རྫོང་ཁག་; Wylie: Bum-thang rzong-khag) is one of the 20 dzongkhag (districts) comprising Bhutan. It is the most historic dzongkhag if the number of ancient temples and sacred sites is counted. Bumthang consists of the four mountain valleys of Ura, Chumey, Tang and Choekhor ("Bumthang"), although occasionally the entire district is referred to as Bumthang valley.
