The black flying squirrel or large black flying squirrel is a species of rodent in the family Sciuridae. It is found in Brunei, Indonesia, and Malaysia; its habitat is primary and secondary forests and gardens where it uses tree hollows. It feeds on fruits, nuts and other vegetable matter.

Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss. The Afghan flying squirrel is usually considered a subspecies.
