Ruff is an English and German surname that originated as a nickname or shortened form from a given name. Etymology The surname Ruff ultimately derives from a nickname for someone with red hair or a ruddy complexion, though in its Germanic usage it is more commonly a derivative of the given name Rolf or its variant Ruf. The name Rolf itself is a reduced form of the Old German name Hrodulf, from the elements hruod “fame” and wolf “wolf.” Therefore, the name Ruff shares the same ancient root as Rudolf: the Germanic name Hrodulf, meaning “famous wolf.” Distribution and Usage The surname Ruff is found mainly in English-speaking countries and German-speaking regions. In England, it may also have originated as an independent surname from the Old English word for “red” (Anglo-Saxon ruff), used for a person with red hair, but this alternative etymology is less secure. In Germany, the name often appears as a patronymic or diminutive from Rolf or Ruf.
