Chesu 车苏 is a Loloish language spoken in southern Shuangbai County, northern Xinping County, and Eshan County in Yunnan, China.

The Chesu refer to themselves as tsu su³³pa²¹^[2] or tɕi²¹su⁵⁵pho²¹ (Jishupo 吉输颇).^[3] Yunnan (1955) reports that Chesu is spoken mostly in Taihe Township 太和乡, with a population of over 360 as of 1955.^[2] Ethnologue reports 3,300 Chesu speakers out of an ethnic population of 6,600 people, as of 2007.^[1]

Bradley (2007) reports that Chesu is closely related to Nasu and classifies it as a Nasoid language. Chesu speakers consider themselves to be a separate ethnic group from the surrounding Nisu speakers. The Chesu language is currently being replaced by Nisu and Chinese.^[4]

In Eshan County, Chesu is also used as a second language by Hlersu speakers.^[1]
