Eadwold of Cerne was a 9th-century prince from East Anglia who later lived as a hermit. Born around 835, he was the son of Æthelweard and was considered a brother to King Edmund. Following a possible Viking invasion, he relocated to a hill near Cerne in Dorset to live a solitary life. Historical accounts, including those by William of Malmesbury, suggest he maintained a strict diet of bread and water while performing various miracles during his time as a recluse.
