The collared peccary (Dicotyles tajacu Linnaeus, 1758) is a vital resource for the subsistence and economy of the Amazonian inhabitants. Despite its importance, there is a notable lack of genetic information on Peruvian collared peccary populations. This study presents the complete mitogenome of D. tajacu from Peru, obtained by Illumina sequencing. The mitochondrial genome spans 16,836 bp and has a nucleotide composition of 34.2 % A, 25.5 % T, 13.5 % G, and 26.8 % C, with a GC content of 40.3 %. The genome includes 13 protein-coding genes, 22 tRNA genes, two rRNA genes, and one control region. Phylogenetic analysis of protein-coding genes indicates that Peruvian D. tajacu is most closely related to Bolivian D. tajacu within the family Tayassuidae. The annotated mitogenome of Peruvian D. tajacu provides valuable genomic data for evolutionary research and will serve in conservation and management strategies for the species.
