The drop bear is a hoax in contemporary Australian folklore featuring a predatory, carnivorous version of the koala. This imaginary animal is commonly spoken about in tall tales designed to scare tourists. While koalas are typically docile herbivores, drop bears are described as unusually large and vicious marsupials that inhabit treetops and attack unsuspecting people that walk beneath them by dropping onto their heads from above.

In North American folklore and American mythology fearsome critters were tall tale animals jokingly said to inhabit the wilderness in or around logging camps, especially in the Great Lakes region. Today, the term may also be applied to similar fabulous beasts.
