Eyvind Lambi or Eyvind Lamb was a Norwegian Viking and hersir of the late ninth and early tenth centuries, known from, among other sources, Egils saga. Eyvind was the son of the Viking Berle-Kari and brother-in-law of Kveldulf Bjalfason, who married Eyvind's sister Salbjorg Karadottir; he was thus uncle to Skalla-Grímr and Thorolf Kveldulfsson and great uncle to the famous poet Egill Skallagrímsson. Eyvind also had a brother named Olvir Hnufa, who became a famous skald at the court of King Harald I of Norway.[1]
