The '''southern deermouse''' or '''southern deer mouse''' ('''''Peromyscus labecula''''') 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". It is found in the United States and Mexico.
== Taxonomy == The species was originally thought to be conspecific with the North American deermouse (now eastern deermouse), ''P. maniculatus'', as ''P. m. labecula'', ''P. m. blandus'', and ''P. m. fulvus''. However, later studies found these subspecies together comprise a distinct species from ''P. maniculatus'', and they were split from ''maniculatus'' in a study published in 2019 as ''P. labecula'', which was followed by the American Society of Mammalogists.<ref name="Greenbaum2019">{{cite journal|author=Greenbaum, I.

In the southern portion of its range, it is sympatric with the similar black-eared mouse (''P. melanotis'').<ref name="Greenbaum2019" /><ref name=":0" />
