The '''blackish deer mouse''' ('''''Peromyscus furvus''''') is a species of [[rodent]] in the family [[Cricetidae]] found only in [[Mexico]], and is relatively poorly studied.

The blackish deer mouse is a relatively large member of its [[genus]], with a total length of {{convert|24|to|28|cm|abbr=on}}, including the {{convert|11|to|14|cm|abbr=on|adj=on}} tail; males are slightly larger than females. As the common name implies, the fur over most of the head and body is a mixture of black and dark brown, giving the animal an overall color that has been described as ''[[bistre]]''. However, the feet, and some cases, the tip of the tail, are white, and the underparts are pale grey. There is a ring of pure black fur around the eyes, while the tail has only a sparse covering of hair. The female has six teats, two in the [[axilla]]ry region, and four in the [[Groin|inguinal]] region.<ref name=Rogers2011>{{cite journal |author1=Rogers, D.S. |author2=Skoy, J.A. |lastauthorampname-list-style=yesamp | year = 2011 | title = ''Peromyscus furvus'' (Rodentia: Cricetidae) | journal = Mammalian Species | volumeissue = 43 | issue = 1 | pages = 209–215 | doi = 10.1644/888.1| doi-access = free }}</ref>

The blackish deer mouse is endemic to [[Mexico]], where it inhabits [[cloud forest]]s, and in nearby forests dominated by [[oak]] and [[pine]]. It prefers environments with heavy undergrowth or cover in the form of rocky cliffs, small caves, or fallen logs. Although its exact range is unclear, it has been collected from the eastern slopes of the [[Sierra Madre Oriental]] mountains between {{convert|650|and|2900|m|abbr=on}} elevation, from [[San Luis Potosi]] in the north to [[Oaxaca]] in the south.<ref name="iucn status 16 November 2021" />

There are no formally recognised subspecies, although genetic analysis of specimens collected in [[Oaxaca]] has shown these may represent an entirely separate species, which has yet to be scientifically described.<ref name=Harris2000>{{cite journal | author = Harris, D. | year = 2000 | title = Phylogeography of ''Peromyscus furvus'' (Rodentia; Muridae) based on cytochrome ''b'' sequence data | journal = Molecular Ecology | volume = 9 | issue = 12 | pages = 2129–2135 | doi = 10.1046/j.1365-294X.2000.01135.x| pmid = 11123624 | s2cid = 18143146 |display-authors=etal}}</ref>
