The Southern red-backed vole is among the smaller voles in Oregon. The pelage is silvery on the venter and grayish with ocherous on the sides, and with a rusty or reddish stripe on the dorsum; the tail is dark brown or black above and whitish or grayish below.

In Oregon it occurs in the Ochoco, Blue, and Wallowa Mountains southwestward to central Crook County and northern Harney County.
