Swæfheard was a king of Kent, reigning jointly with Oswine, Wihtred, and possibly Swæfberht.
Swæfheard's charter[1] dated 1 March 689, in the second year of his reign, identifies his father as Sæbbi, King of Essex (ac consensu patris mei Sebbe regis).
He witnessed two charters of Oswine,[2][3] one of which is dated 27 January 690.
Swæfheard apparently ruled West Kent as a sub king under his father,[4] while Oswine ruled the eastern half.
According to Bede, Swæfheard was still reigning jointly with Withred in July 692.
