We present the complete mitochondrial genome and a phylogenetic analysis of Callorhinus ursinus, the northern fur seal, determined using Illumina next-generation sequencing (NGS) technology. The total length of the mitogenome was 17,154 bp, which consisted of 13 protein-coding genes, two ribosomal RNA genes, 22 tRNA genes, and one control region. The base composition of the entire mitogenome was 33.5% (A), 26.3% (C), 13.9% (G), and 26.3% (T) with an A + T bias of 59.8%. The control region contained two types of tandem repeats. A neighbour-joining (NJ) tree was constructed and comprised two clades with C. ursinus forming a monophyletic group. Data produced in this study will aid exploration of the genetic diversity of endangered C. ursinus and contribute to molecular identification of this species.
