Rusa unicolor, including seven subspecies, has been listed as a vulnerable species by the International Union for Conservation of Nature and Natural Resources. The mitochondrial genome has proven to be a highly successful resource for investigation of evolution and population genetics. In this study, the complete mitochondrial genome of Rusa unicolor hainana was sequenced and analyzed. The circle genome was found to be 16,436 bp in length, containing 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and one noncoding control region. Additionally, maximum likelihood and Bayesian inference trees were conducted based on the 13 PCGs of species within the Cervinae subfamily. The phylogenetic tree demonstrated that R. u. dejeani is more closely related to R. u. swinhoei than to R. u. hainana. This study could provide important molecular data for species identification and the phylogenetic relationship of R. unicolor.
