Chiefdom of Sizhou (Chinese: 思州土司; pinyin: Sīzhōu Tǔsī), ruled by the Tian clan, was an autonomous Tusi chiefdom established by Tian Zongxian (田宗顯) during the Sui dynasty. After he conquered the Qianzhong area (present-day eastern Guizhou Province), Tian Zongxian was recognized as the hereditary ruler of the region by the Sui court in 582.

Sizhou, Bozhou, Shuidong and Shuixi were called "Four Great Native Chiefdom in Guizhou" (贵州四大土司) by Chinese. "Liangguang [ruled by] Cen and Huang, Sizhou and Bozhou [ruled by] Tian and Yang" (Chinese: 两广岑黄,思播田杨; pinyin: Liǎngguǎng Cén Huáng, Sī Bō Tián Yáng), an idiom current among Southwestern Mandarin speakers, proved that the Tian clan was once one of the most powerful clans in Southwestern China.
