Hang Dong is a district (amphoe) of Chiang Mai Province in northern Thailand. Neighbouring districts are (from the southwest clockwise) San Pa Tong, Mae Wang, Samoeng, Mae Rim, Mueang Chiang Mai, Saraphi of Chiang Mai Province, and Mueang Lamphun of Lamphun Province.
The village Ban Tawai in Khun Khong sub-district is known for its handicraft center, as wood carving has been a local speciality since the 1960s.
Before 1917, the district was named Mae Tha Chan. In 1938 the district was downgraded to a minor district (king amphoe) and made subordinate to Mueang Chiang Mai District. In 1947 it was elevated to full district status again.
