Frithwald (Old English: Friþuweald[1] or Friðewald;[2] d. 762 × 764) was an Anglo-Saxon Bishop of Whithorn.
[3] The only other source for Frithwald is the entry in versions D and E of the Anglo-Saxon Chronicle which, sub anno 762, relate that:Frithwald, bishop at Whithorn, died on the Nones of May [May 7].
He was consecrated at Chester on the eighteenth before the Kalends of September [August 15], in the sixth winter of Ceolwulf's kingship [734/5]; and he was bishop twenty-nine winters[4]Friþuweald biscop æt Hwiterne forðferde on Nonas Maius, se wæs gehalgod on Ceastre on .xviii.
wintra Ceolwulfes rices, 7 he wæs biscop .xxix.
[1] If the Worcester source is correct, that would put his death in 764; the entry is also sometimes thought to cover the year 763.
