The freshwater crocodile (Crocodylus johnsoni or Crocodylus johnstoni; see below), also known as the Australian freshwater crocodile, Johnstone's crocodile or colloquially as freshie, is a species of reptile endemic to the northern regions of Australia.

Unlike their much larger Australian relative, the saltwater crocodile, freshwater crocodiles are not known as man-eaters and rarely cause fatalities, although they will bite in self-defense if cornered.
