Frithwald (Old English: Friþuweald[1] or Friðewald;[2] d. 762 × 764) was an Anglo-Saxon Bishop of Whithorn. The version of the Anglo-Saxon Chronicle in the Worcester Chronicle says that in 735 he succeeded Pehthelm, after the latter's death, as 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]If the Worcester source is correct, that would put his death in 764; the entry is also sometimes thought to cover the year 763.[5]
