Æthelberht (Old English: Æðelbrihte), also called Saint Ethelbert the King, (died 20 May 794 at Sutton Walls, Herefordshire) was an eighth-century saint and a king of East Anglia, the Anglo-Saxon kingdom which today includes the English counties of Norfolk and Suffolk. Little is known of his reign, which may have begun in 779, according to later sources, and very few of the coins issued during his reign have been discovered. It is known from the Anglo-Saxon Chronicle that he was killed on the orders of Offa of Mercia in 794.
