Æthelberht II was an 8th-century king of the East Anglian kingdom, which encompassed modern-day Norfolk and Suffolk. Though historical details regarding his reign are scarce, he is remembered as a pious ruler. His life ended violently in 794 when he was executed on the orders of Offa of Mercia, possibly due to tensions regarding his political independence. Following his death, he was recognized as a saint, and his memory was preserved through religious devotion in both East Anglia and Hereford.
