In this study, the complete mitochondrial genome of short-tailed field vole, Microtus agrestis, was determined through sequencing of PCR fragments. The complete mitochondrial genome of M. agrestis was 16,538 bp in length and encoded 13 protein-coding genes, 22 transfer RNA (tRNA) genes, and two ribosomal RNA genes. The overall nucleotide composition is: 15.7% A, 27.5% T, 25.5% C, and 31.4% G, with a total G + C content of 56.9%. By phylogenetic analysis using Bayesian method, M. agrestisa showed the closest relationship with the southern vole (Microtus rossiaemeridionalis).
