Eremoryzomys polius, also known as the Grey Rice Rat or the Maranon Oryzomys, is a species of rodent in the family Cricetidae that is only found in the valley of Rio Maranon in the northern Andes of Peru. Although it has long been placed in the genus Oryzomys, it is now considered the only member of the separate genus Eremoryzomys, which is sister to a clade containing, among others, Holochilus, Nectomys and Oryzomys in the strict sense. The generic name combines the Ancient Greek word erimia for "lonely place" with the name Oryzomys and stresses the lonely location of the distribution of the species.

The dorsal pelage is gray, but the ventrum is white. It has short ears. There are tufts of hair at the base of the claws on the hindfoot. The long tail is darker above than below.
