We present the complete mitochondrial genome of the Trachinotus ovatus in this study. The mitochondrial genome is 16,563 bp long and consists of 13 protein-coding genes, two rRNA genes, 22 tRNA genes and a control region. The gene order and composition of T. ovatus mitochondrial genome was similar to that of most other vertebrates. The nucleotide compositions of the light strand are 29.03% of A, 28.86% of C, 26.23% of T and 15.88% of G. With the exception of ND6 and eight tRNA genes, all other mitochondrial genes are encoded on the heavy strand. Two copies of tandem repeat sequence (56 bp) was observed in the 5' end of the control region.
