Budic II (; or ; ), formerly known as
Budick, was a king of
Cornouaille in
Brittany in the late 5th and early 6th centuries. He was the father of
Hoel Mawr and is probably to be identified with the
Emyr Llydaw ("Emperor of
Brittany") and
King Nentres who appear in
Arthurian legend. Upon his death, his kingdom was usurped by Macliau, king of the neighboring
Veneti.
