French naturalist Étienne Louis Geoffroy described the long-nosed bandicoot in 1804.
Swiss naturalist Heinrich Rudolf Schinz described a large specimen from near Bathurst in the Blue Mountains as a new species, Perameles lawson, in 1825, though the specimen was lost at sea in shipwreck.
French naturalist Pierre Boitard described Isoodon musei in 1841, both are now classified as P. nasuta.

Two subspecies are recognised: P. nasuta subspecies nasuta is found from western Victoria through eastern New South Wales and north to central Queensland, and  P. nasuta subspecies pallescens, found from central Queensland through to the Cape York Peninsula.

The long-nosed bandicoot is the largest member of its genus, which also includes the eastern barred bandicoot and the western barred bandicoot.
It is most closely related to the eastern barred bandicoot, the two species having diverged from one another in the late Pliocene.
Their ancestors diverged from the ancestor of the western barred bandicoot in the Miocene.
