King Hoel (,  "Hoel the Great"), also known as Sir Howel and Saint Hywel, was a late 5th- and early 6th-century member of the ruling dynasty of Cornouaille. He may have ruled Cornouaille jointly after the restoration of his father Budic II, but he seems to have predeceased his father and left his young son Tewdwr as Budic's heir.
