The flying squirrels, scientifically known as Pteromyini or Petauristini, are a tribe of squirrels (family Sciuridae). There are 43 species in this tribe, the largest of which is the woolly flying squirrel ("Eupetaurus cinereus"). The two species of the genus "Glaucomys" ("Glaucomys sabrinus" and "Glaucomys volans") are native to North America, and the Siberian flying squirrel is native to parts of northern Europe ("Pteromys volans").

The term "flying" is somewhat misleading, since flying squirrels are actually gliders incapable of true flight. Steering is accomplished by adjusting tautness of the patagium, largely controlled by a small cartilaginous wrist bone. The tail acts as a stabilizer in flight, much like the tail of a kite, and as an adjunct airfoil when "braking" prior to landing on a tree trunk.

Though their life expectancy is only about six years in the wild, flying squirrels often live between 10 and 15 years in captivity. This difference is due to these creatures being important prey animals. Predation mortality rates in sub-adults are very high. Predators include arboreal snakes, raccoons, nocturnal owls, martens, fishers, coyotes, and the domestic house cat. In the Pacific Northwest of North America, the Northern Spotted Owl ("Strix occidentalis") is a well-known predator. They are also nocturnal.

They have been kept as pets since the US colonial era.

**Subtribe Glaucomyina
***"Eoglaucomys", one species, the Kashmir Flying Squirrel ("Eoglaucomys fimbriatus").
***"Glaucomys" (American flying squirrels), two species, the Northern flying squirrel and the Southern flying squirrel, North America
***"Hylopetes", seven species, southeast Asia
***"Iomys", one species, Horsfield's Flying Squirrel, Malaysia and Indonesia
***"Petaurillus" (pygmy flying squirrels), three species, Borneo and Malaya
***"Petinomys", nine species, southeast Asia

***"Aeretes", one species, the Groove-toothed Flying Squirrel or North Chinese Flying Squirrel ("A. melanopterus"), northeast China
***"Aeromys", two species, Thailand to Borneo
***"Belomys", one species, the hairy-footed flying squirrel ("B. pearsonii"), southeast Asia.
***"Biswamoyopterus", one species, the Namdapha flying squirrel, India
