à ÂwiÃÂtobor () was a Pomeranian duke of 11th and 12th century. According to Gesta principum Polonorum of the chronicler Gallus Anonymus, he was a relative of king of Poland, Bolesà Âaw III Wrymouth. In one particular instance, à ÂwiÃÂtobor was imprisoned by his rivals and Bolesà Âaw set out with military aid for à ÂwiÃÂtobór. However, before Bolesà Âaw's expedition reached its destination, à ÂwiÃÂtobór was freed and the king's forces turned around and returned home.
As historical sources do not mention anything else about him, remaining information on à ÂwiÃÂtobór consists of speculation. Historians assume that he was a ruler of part of Western Pomerania and a descendant of Siemomysà  of Pomerania and a relative of à ÂwiÃÂtopeà Âk, Duke of Pomerania. Modern historians assume that Siemomysà  was a descendant of à ÂwiÃÂtopeà Âk Mieszkowic or Mieszko Mieszkowic.
