Uriankhai (traditional Mongolian: ᠤᠷᠢᠶᠠᠩᠬᠠᠢ, Mongolian Cyrillic: урианхай; Yakut: урааҥхай; simplified Chinese: 乌梁海; traditional Chinese: 烏梁海; pinyin: Wūliánghǎi), Uriankhan (ᠤᠷᠢᠶᠠᠩᠬᠠᠨ, урианхан) or Uriankhat (ᠤᠷᠢᠶᠠᠩᠬᠠᠳ, урианхад), 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 兀良哈 (pinyin: Wùliánghā).
