The Nelson's Rice Rat ("Oryzomys nelsoni") is an extinct species of rice rat from damp thickets in the vicinity of springs near the summit of Maria Madre Island, Nayarit, in the Tres Marias Group, off the coast of western Mexico. Four specimens were collected on 18 May 1897. The rice rat may have disappeared due to introduced rats and cats. It has been considered to be a subspecies of the Marsh Rice Rat ("Oryzomys palustris"), but it is now universally recognized as a separate species. It was the only sigmodontine rodent endemic to a Mexican island.

The specific name of this species commemorates the American naturalist Edward William Nelson.
