Pengshui Miao and Tujia Autonomous County is an autonomous county for the Miao and Tujia people located in southeastern Chongqing, China, bordering Guizhou province to the south and southwest and Hubei province to the northeast. It is 270 kilometres (170 mi) away from downtown Chongqing.

The Miao are a group of linguistically related peoples living in Southern China and Southeast Asia, who are recognized by the government of China as one of the 56 official ethnic groups. The Miao live primarily in the mountains of southern China. Their homeland encompasses the provinces of Guizhou, Yunnan, Sichuan, Hubei, Hunan, Guangxi, Guangdong, and Hainan. Some sub-groups of the Miao, most notably the Hmong people, have migrated out of China into Southeast Asia. Following the communist takeover of Laos in 1975, a large group of Hmong refugees resettled in several Western nations, mainly in the United States, France, and Australia.
