Wihthun (died) was an early medieval Bishop of Selsey.
Wihthun seems to have been appointed bishop in 789, as he appears last among the bishops in the witness list of a charter issued by Osfrith, King of Mercia, to Wærmund, Bishop of Rochester in that year.
Wihthun's last datable subscriptions are to two charters of 805: a grant by Cuthred, King of Kent, to Archbishop Wulfred, and a grant by Coenwulf, King of Mercia, and Cuthred, King of Kent, to a priest called Wulfhard.[1] He also witnessed a grant from between 805 and 807 by Cuthred, King of Kent, to Æthelnoth, praefectus.[2]
Wihthun died sometime after 805 and before 811.[3]
