The Okinawa flying fox (Pteropus loochoensis) is a species of megabat in the Pteropus genus. It is endemic to possibly Japan. It was previously listed as extinct by the IUCN, but because the two known specimens are taxonomically uncertain and of unknown provenance, it was changed to 'Data Deficient'. Some place this animal into synonymy under Pteropus mariannus. Others treat the Okinawa flying fox as a subspecies of the latter, while some give it full species status.
