Heller's vlei rat (Otomys helleri) is a species of rodent in the family of Muridae.

It is endemic to Ethiopia and is found on the Arussi Plateau and the Bale Mountains.

[1][3] Childs Frick (1914) initially described this species under the name Otomys jacksoni helleri.

It was then included under O. typus (Ethiopian vlei rat) as a subspecies, and later as a synonym until Taylor et al. (2011) would elevated the taxa to species status.

[4][1] It is listed as "Least Concern" by the IUCN, due to a vast area of occurrence.
