The Simien vlei rat (Otomys simiensis)[1][3] is a species of rodent in the family Muridae.

It is found in northern Ethiopia.

[1] The species is known from less than 10 locations in Ethiopia.

However, it is thought to occur in a protected area, which justified the reasoning behind the "Least Concern" assessment by the IUCN.
