Wermund, Vermund or Garmund is an ancestor of the Mercian royal family, a son of Wihtlaeg and father of Offa. The Anglo-Saxon Chronicle makes him a grandson of Woden, but the Gesta Danorum written by Saxo Grammaticus goes no further than his father, while the Brevis Historia Regum Dacie of Sven Aggesen makes Wermund son of king Frothi hin Frokni.
