Dachanghe (Chinese: 大長和; lit. 'Great Long Harmony'), possibly Da Changhe or Changhe, was a monarchy from 902 to 928 in modern Yunnan, China. Founded by Zheng Maisi (鄭買嗣), it was the successor state of Nanzhao (738–902), whose ruling Meng (蒙) family was mass-murdered in a bloody coup by Zheng. The Zheng family suffered a similar fate 26 years later at the hands of Yang Ganzhen (楊干貞), who helped found a state named Datianxing (大天興) (928–929).

Zheng Maisi changed his name to Zheng Anguo and declared the reign era Anguo. His successor, Zheng Renmin, attacked Former Shu in 914 but suffered a heavy defeat. Renmin sent his grand councillor (buxie), Duan Yizong, to Former Shu, possibly to secure a marriage alliance. In 925, another mission led by the buxie Zheng Zhaochun secured a marriage alliance with Southern Han, whose ruler gave his daughter, the Zengcheng Princess, as wife. In 927, Later Tang defeated Former Shu and returned thousands of captives to Dachanghe.
