The Shatuo, or the Shatuo Turks (; also transcribed as Sha-t'o, Sanskrit Sart) were a Turkic tribe that heavily influenced northern Chinese politics from the late ninth century through the tenth century. They are noted for founding three, Later Tang, Later Jin, and Later Han, of the five dynasties and one, Northern Han, of the ten kingdoms during the Five Dynasties and Ten Kingdoms period. The Northern Han would later be conquered by the Song dynasty. Sometime before the 12th century, the Shatuo disappeared as a distinct ethnic group, many of them having become acculturated and assimilating into the general population around them.
The Shatuo tribe were descended mainly from the Western Turkic Chuyue tribe, who in turn belonged to a group of four Chuy tribes, collectively known as Yueban. The Yueban state survived to the end of the 480s when its independence was destroyed by the Tiele people. After the fall of the state, the people of Yueban formed four tribes - Chuyue, Chumi, Chumuhun and Chuban. These tribes became major players in the later First Turkic Khaganate and thereafter. The Chuyue and Chumi did not belong to the dominant Onoq (Ten Arrows) Union, while Chumukun and Chuban did.
Other sources claim the Shatuo originated from the Tiele. The epitaph of Shatuo Li Keyong, a late-Tang military commissioner (jiedushi), states that his clan's progenitor was "Yidu, Lord of the Xueyantuo state, an unrivaled general" (益度、薛延陀國君、無敵將軍), Xueyantuo was a Tiele tribe. Other Chinese chroniclers traced the Shatuo's origins to a Tiele chief named *Bayar (拔也 Baye) ~ *Bayïrku (拔也古 Bayegu) The Song historian Ouyang Xiu rejected the Bayïrku origin of Shatuo; he pointed out that the Bayïrku were contemporaries, not primordial ancestors, of the Shatuo's reigning clan Zhuxie, and that this Western Turkic kin-group adopted Shatuo as their tribal name and Zhuxie as surname after their chief Jinzhong (盡忠; lit. "Loyal to the Utmost") had moved into Beiting Protectorate, in Tang Dezong's time (r. 780 - 804).
