Haa District (Dzongkha: ཧཱ་; Wylie: Haa; alternative spellings include "Ha") is one of the 20 dzongkhag or districts comprising Bhutan. Per the 2005 census, the population of Haa dzongkhag was 11,648, making it the second least populated dzongkhag in Bhutan after Gasa. The dominant language of the district is Dzongkha, the national language.
Haa's major feature is the Haa Valley, a steep north-south valley with a narrow floor. The name Haa (pronounced "hah"), as well as the more ancient name Has (Dzongkha: ཧས་; Wylie: Has; pronounced "hay"), connotes esoteric hiddenness. An alternative name for the district is "Hidden-Land Rice Valley."
The main crops grown in the valley are wheat and barley, although some rice is grown in the lower reaches of the valley. Potatoes, chilis, apples and other cash crops are grown by farmers on the valley floor, along terraced hillsides, and in some of the more accessible side valleys. Per the census, almost every household owns livestock of some type, most commonly yaks and cattle, but also chickens, pigs, and horses. 78% of Haa is covered with forest, and forestry plays an important part in local economy.
