The Tres Marias Island Mouse (Peromyscus madrensis) is a species of rodent in the family Cricetidae. It is found only on the Islas Marías off the west coast of Mexico (part of the state of Nayarit). When last assessed, it was common on María Cleofás Island, but rare or absent on the other, more disturbed, islands.[1]
