The Bismarck flying fox (Pteropus neohibernicus) is also known as the great flying fox or greater flying fox and is a megabat of the family Pteropodidae. These megabats are also called Old World fruits bats. Several contradicting pieces of evidence suggest that these species are close relatives of the spectacled flying fox or both the Pelew and insular flying foxes. These bats are the heaviest in the world and are the largest bats in Melanesia. These bats roost with many individuals in their life.

Wilheim Peters, a German naturalist, first described this species in the year 1876 after Carl Hüsker had collected a single holotype from Papua New Guinea. The specific name 'neohibernicus' is a Latin word meaning 'new Ireland'. The two recognized subspecies of these bats are P. n. hill and P. n. neohibernicus. Due to varying coloration, they have various taxonomic synonyms, including Pteropus degener. As per a 2019 study, the Pteropus genus is most closely related to the spectacled flying fox. Their suborder is Yinpterochiroptera and these species can cause various diseases in humans, including the Hendra virus.
