The complete mitochondrial genome of Eaton’s skate Bathyraja eatonii was studied using the long-read technology, PacBio Sequel System. The complete mitochondrial genome form of B. eatonii was 16,698 bp and it’s comprised of 13 protein-coding genes, 22 tRNA and 2 rRNA. The base composition of B. eatonii is analyzed 31.94% for A, 33.94% for T, 13.49% for G, 20.64% for C, the result of GC content was 33.94%. Phylogenetic analysis showed that B. eatonii was closely related to Bathyraja meridionalis in Arhynchobatidae family, and this first mitochondrial genome of Antarctic skate would provide fundamental information to the evolutional relationship of Antarctic fishes
