A feral pig (from Latin fera, "a wild beast") is a pig (Sus scrofa) living in the wild but which has descended from domesticated individuals.
Razorback and wild hog are American colloquialisms, loosely applied to any type of feral domestic pig, wild boar or hybrid in North America; pure wild boar are sometimes called "Russian boar" or "Russian razorbacks". The term "razorback" has also appeared in Australia, to describe feral pigs there.
