Aphid gossypii Glover, 1877 is a widely recognized economically important aphid species in the world. We have determined mitochondrial genome of A. gossypii collected in Korean peninsula. The circular mitogenome of A. gossypii is 15,872 bp including 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNAs, and a single control region of 627 bp. The base composition was AT-biased (83.8\%). In comparison of Chinese A. gossypii mitochondrial genomes with that of Korean sample, 61 single nucleotide polymorphisms and 3 insertions and deletions were identified, presenting lower level of those of Nilaparvata lugens, Laodelphax striatellus, and Chilo suppresallis.
