Rikiwulf ("The rich and powerful wolf" or "The Ruler of the wolves") was a member of the Wulfing dynasty, mentioned in the Beowulf saga. In 880 AD, he sailed with his Viking warriors from Ghent up the river Lys in Flanders, and settled in succession Rikiwulfinga-haim near Tielt, Rekkem near Menin, and Richebourg, Reclinghem, Racquinghem and Erquinghem-Lys in present Artois, France.
