Camponotus concavus Kim & Kim, 1994 is a large carpenter ant endemic to the Korean peninsula. We have determined the mitochondrial genome of C. concavus. The circular mitogenome of C. concavus is 16,357 bp including 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNAs, and a single large non-coding region of 985 bp. The base composition was AT-biased (77.7\%). Gene order of C. concavus is identical to Camponotus atrox and differs in one tRNA from Polyrhachis dives, all of which belong to tribe Camponotini. Phylogenetic tree agrees with the current phylogenetic placement of C. concavus sister to all other Camponotus mitogenomes within the tribe Camponotini. The mitochondrial genome of C. concavus will be a good resource for understanding the species in aspect of molecular phylogeny.
