The Achang (Chinese: 阿昌族; pinyin: Āchāng zú), also known as the Ngac'ang (their own name) or Maingtha (Burmese: မိုင်းသာလူမျိုး) are an ethnic group. They form one of the 56 ethnic groups officially recognized by the People's Republic of China. They also live in Burma.
The Achang number 27,700, of whom 27,600 are from Yunnan province, especially Dehong Autonomous Prefecture. The Achang speak a Burmish (Burmese-related) language called Achang, but there is no indigenous writing system to accompany it. Chinese characters are often used instead.
The ancestors of the Achang were some of the first inhabitants of the province of Yunnan. Their ancestors lived near the Lancang river and during the 12th century they began to emigrate towards the border the west of the river. By the 13th century, some of them settled down in the area of Longchuan, whereas others settled around Lianghe.

The men usually use the colors blue, or black to make their shirts, buttoned to a side. Unmarried men surround their head with a fabric of white color, whereas married men wear blue.
