The mamore arboreal rice rat (Oecomys mamorae), also known as the Mamore oecomys, is an arboreal species of rodent in the genus Oecomys of family Cricetidae. Its distribution extends over much of Bolivia and into nearby Brazil and Paraguay. Although Oecomys has been recorded from Argentina, it is uncertain whether those records represent O. mamorae. It is found in a variety of habitats at elevations from 200 to 2,100 m (660 to 6,890 ft), where it feeds on fruit and green seeds.
