William II of Bures (died 1158) was a Crusader lord of the Kingdom of Jerusalem. He was Prince of Galilee from 1148 to his death as successor of his brother Elinand.
William is a poorly known figure. It is known that he was a nephew of William I of Bures and as this William is only known to have one brother, Godfrey, it is presumed that William and his three known brothers and one sister were children of his.
William was succeeded in Galilee by his sister Eschiva.
