Æthelmund, an Anglo-Saxon noble, was Ealdorman of Hwicce in the late 8th century, perhaps living into the early 9th century. Æthelmund's predecessors had been kings, but he was a subject of the king of Mercia.
In 770 Uhtred of Hwicce issued a charter to his thegn Æthelmund [1].
Later, between 793 and 796 [2] Earldorman Æthelmund witnessed a charter of Offa, King of Mercia.
In 796 Ecgfrith, King of Mercia, granted land to Æthelmund, now styled princeps [3].
He seems to have been succeeded by his son Æthelric, who issued a charter in 804 [4], in which he gave land to his mother, Ceolburh, presumably Æthelmund's widow.
