The Guizhou snub-nosed monkey (Rhinopithecus brelichi) is an endangered species which is endemic to a small region in the fanjing mountain national nature reserve in Guizhou province, China. In this study, we determined the complete mitochondrial genome of R. brelichi. The results showed that the total length of the mitogenome was 16,548 bp and contained 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes and one control region. Overall base composition of the complete mitochondrial DNA was 32.35% A, 29.28% T, 25.54% C and 12.83% G. All the genes in R. brelichi were distributed on the H-strand, except for the ND6 subunit gene and eight tRNA genes which were encoded on the L-strand.
