Caradoc Freichfras was a 5th or 6th-century Celtic king, potentially ruling the kingdom of Gwent from Caerwent. His nickname, which can be interpreted as Strongarm or Shortarm, is associated with his identity as a military leader in South Wales or Brittany. Within various traditions, he is recognized as a semi-legendary progenitor of the kings of Gwent. He is also remembered through Arthurian lore as a knight of the Round Table and a ruler of Cornwall under Octavius.
