Deerman (deer + man) is a variety of regional folkloric creatures that are described as having combined traits of a deer and a human being, often with the head (and horns), the hind legs, and the hooves of the deer, and the torso and arms of the human being, or having only the head of the deer and appearing otherwise human. It may be considered distinct from the Deer Woman or Deer Lady that appears in varied mythologies of the indigenous peoples of North America.
