Eadberht I was king of Kent from 725 to 748. After his father, Wihtred of Kent died, he inherited the kingdom of Kent along with his two brothers Æðelberht II and Alric. Æðelberht II seems to have been the eldest and more dominant brother. Eadberht I died in 748, according to the Anglo-Saxon Chronicle. He left a son, Eardwulf, who succeeded as king jointly with his uncle.
His one complete surviving charter apparently dates from 14 October 727 . Another charter, is an altered copy of one issued by Æðelberht II (Sawyer 1968). Other charters attributed to Eadberht I are copies of charters of Eadberht II with “deliberate chronological falsification” (Kelly 1995).
