In American folklore, a Sidehill gouger is a fearsome critter adapted to living on hillsides by having legs on one side of their body shorter than the legs on the opposite side, having evolved to resemble any form of mammals such as pangolins, goats, humans, and bears. This peculiarity allows them to walk on steep hillsides, although only in one direction; when lured or chased into the plain, they are trapped in an endless circular path. Some claim these creatures play a large role in, and in some cases are responsible for, the creation of hoodoos. The creature is variously known as the Sidehill Dodger, Sidehill Hoofer, Side-hill Gazink, Sidehill Ousel, Sidehill Loper, Sidehill Galoot, Gyascutus, Sidewinder, Wampus, Boofum, Gudaphro, Hunkus, Rickaboo Racker, Prock, Gwinter, or Cutter Cuss.

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.
