Billy Blind (also known as Billy Blin, Billy Blynde, Billie Blin, or Belly Blin) is an English and Lowland Scottish household spirit, much like a brownie. He appears only in ballads, where he frequently advises the characters. It is possible that the character of Billy Blind is a folk memory of the god Woden or Odin from Germanic mythology, in his "more playful aspect" and is speculated to have been the same character as Blind Harie, the "blind man of the game" in Scotland.
