Uriankhai, Uriankhan or Uriankhat, is a term of address applied by the Mongols to a group of forest peoples of the North, who include the Turkic-speaking Tuvans and Yakuts, while sometimes it is also applied to the Mongolian-speaking Altai Uriankhai. The Uriankhai included the western forest Uriankhai tribe and the Transbaikal Uriankhai tribe, with the former recorded in Chinese sources as Chinese: 兀良哈; pinyin: Wùliánghā). It is the origin of the Korean term "barbarian", 오랑캐.

The Tuvans or Tyvans are a Turkic ethnic group indigenous to Siberia who live in Russia (Tuva), Mongolia, and China. They speak Tuvan, a Siberian Turkic language. In Mongolia they are regarded as one of the Uriankhai people groups.
