* Southern flying squirrel: Found in the eastern and southeastern United States.
* Virginia opossum: Found throughout North America, though not technically a "flying squirrel" but is also a gliding mammal.

* European flying squirrel: Found in parts of Europe, including Scandinavia, Russia, and some parts of Central Europe.
Asia:
* Japanese dwarf flying squirrel: Found in Japan.
