Chuanchia labiosa Herzenstein, 1891 (Cyprinidae: Schizothoracinae) is the sole species of genus Chuanchia and is endemic to China. This species plays an important role in the upper reaches of the Yellow River and has been listed in both the China Red Data Book of Endangered Animal and the China Species Red List. In this study, the complete mitochondrial DNA genome sequence of C. labiosa was determined. The mitogenome is 16,705 bp in length, including 13 protein-coding genes, 22 tRNA genes, two rRNA genes, and two non-coding regions. Overall basic composition of mitochondrial genome of C. labiosa is 28.39% for A, 27.16% for T, 26.09% for C, and 18.36% for G with a slightly high A + T content (55.55%). The complete mitogenome sequence of C. labiosa would be useful for stock evaluation and further conservation genetic studies for this endangered species.
