Eanmund was a Swedish prince of the Scylfing dynasty. Unlike his relatives, Eanmund is only mentioned in Beowulf. Eanmund was the son of Ohthere and the brother of Eadgils. Ohthere was murdered by his younger brother Onela, who claimed the Swedish throne. Since, their uncle had usurped the throne and murdered their father, Eanmund and Eadgils sought refuge among the Geats. This caused Onela to attack the Geats, an attack which was also motivated by the fact that the Geatish king Heardred's father had killed Onela's grand-father Ongentheow. During the battle, Eanmund was killed by Onela's champion Weohstan and Heardred was killed as well. Eadgils, however, survived and later, Beowulf helped him avenge Eanmund and Ohthere by slaying Onela, an event which also appears in Scandinavian sources.

Weohstan took Eanmund's sword which was inherited by his son Wiglaf who used the sword when fighting the dragon together with Beowulf.
