Eardwulf was king of Kent, reigning jointly with Æðelberht II.
Eardwulf is known from two charters, one of which is undated,[1] but identifies Eardwulf's father as Eadberht I (a patre meo Eadberhtuo); the other has a date that is incompatible with its witness list,[2] as it is dated 762, but witnessed by Archbishop Cuðbert, who died in 760; it was also witnessed by King Æðelberht II (Aethilberchtus rex Cantie).
