In the present work, the complete mitochondrial genome of the Triplophysa strauchii (Cypriniformes: Cyprinidae, Balitoridae, Cobitoidea) is sequenced and placed, the phylogenetic analysis with another individual of Triplophysa fishes was carried out. The mitogenome is 16,590 bp in length, consisting 13 protein genes, 22 tRNA genes, 2 rRNA genes, and 2 non-coding regions. The total base composition is 28.26%, 28.49%, 25.42% and 17.82% for A, T, C and G, respectively. All genes were encoded on the heavy strand except for ND6 and 8 tRNA genes. These results will provide useful data for species identification and genetic study of Triplophysa fishes.
