The Kumo Xi (traditional Chinese: 庫莫奚; simplified Chinese: 库莫奚; pinyin: Kùmò Xī^[1]), also known as the Tatabi, were ancient steppe people located in current Northeast China from 207 CE to 907 CE. After the death of their ancestor Tadun in 207, they were no longer called Wuhuan but joined the Khitan Xianbei in submitting to the Yuwen Xianbei. Their history is widely linked to the more famous Khitan.^[2]

During their history, the Kumo Xi engaged in conflict with numerous Chinese dynasties and with the Khitan tribes, eventually suffering a series of disastrous defeats to Chinese armies and coming under the domination of the Khitans. In 907, the Kumo Xi were completely assimilated into the Khitan-led Liao dynasty of China.
