Morgan Tud is the head physician of King Arthur's court in early Arthurian tales.
In the medieval tale, Geraint son of Erbin, Morgan is called to treat Edern ap Nudd, Knight of the Sparrowhawk, following the latter's defeat at the hands of his adversary Geraint. He is later called on by Arthur to treat Geraint himself, and stayed for almost a month nursing the knight. When Geraint claims that he has healed, Arthur calls on Morgan to deliver his verdict before allowing Geraint to leave his sick-bed.
