Hylaeamys laticeps, also known as the Atlantic Forest oryzomys^[2] or the large-headed rice rat,^[1] is a species of rodent in the family Cricetidae.

The rodent is endemic to the Atlantic Forest region of southeastern Brazil.^[1]

The taxonomic history of Hylaeamys laticeps has been complex, and the name laticeps has been used for various members of the genera Cerradomys, Euryoryzomys, Transandinomys and Hylaeamys at different times. Until 2006, it was classified in the genus Oryzomys as Oryzomys laticeps. The species Oryzomys seuanezi is now a junior synonym of H. laticeps.^[3]
