Peromyscus is a genus of rodents. They are commonly referred to as deer mice or deermice, not to be confused with the chevrotain or "mouse deer". They are New World mice only distantly related to the common house and laboratory mouse, Mus musculus. From this relative, Peromyscus species are distinguished by relatively larger eyes, and also often two-tone coloring, with darker colors over the dorsum (back), and white abdominal and limb hair-coloring. In reference to the coloring, the word Peromyscus comes from Greek words meaning "booted mouse". They are also accomplished jumpers and runners by comparison to house mice, and their common name of "deer mouse" is in reference to this agility.
Schmidly's deer mouse, is a recently described species of deer mouse from the mountains of western Mexico. It is part of the highly complex and well-studied Peromyscus boylii species complex. The uniqueness of Peromyscus from this area had long been suspected, but was only formalized in 2004 with the publication of its species description. The species was named in honor of David J. Schmidly, a mammalogist and former president of the University of New Mexico.

The cactus mouse is a species of rodent in the family Cricetidae. It is a species of the genus Peromyscus, a closely related group of New World mice often called "deermice". They are native to desert areas of southwestern North America.

The Angel Island mouse, or La Guarda deermouse, is a species of rodent in the family Cricetidae.
Hooper's mouse is a species of rodent in the family Cricetidae. It is the only member of the Peromyscus hooperi species group, and is found only in Mexico. The species is named for Emmett Hooper, a researcher into the taxonomy of the genus Peromyscus.
The Tres Marías island mouse or Tres Marías deer mouse is a species of rodent in the family Cricetidae. It is found only on the Islas Marías off the west coast of Mexico. When last assessed, it was common on María Cleofás Island, but rare or absent on the other, more disturbed, islands.
The black-eared mouse, or black-eared deer mouse, is a species of rodent in the family Cricetidae, native to North America.
The Mexican deer mouse is a species of forest-dwelling rodent in the family Cricetidae. It is found in southern Mexico and throughout much of Central America.
The tawny deer mouse or marsh mouse is a species of rodent in the family Cricetidae. It is found only in Mexico.
The false canyon mouse or Coronados deer mouse, is a species of rodent in the family Cricetidae. It is known only from Coronados Island, a small island in the Gulf of California, part of Baja California Sur, Mexico. The species is threatened by predation by feral cats, and the IUCN has assessed its conservation status as "critically endangered".

The Northern Baja deer mouse is a species of deer mouse native to Southern California and the Baja California peninsula as well as several islands in the Gulf of California. P. fraterculus was previously considered a subspecies of the cactus mouse prior to a 2000 study which identified genetic differences and suggested P. fraterculus is more closely related to Eva's desert mouse than to P. eremicus.
