In Wales and England, this saint is known by his birth and baptismal name Kentigern (). This name probably comes from the British *"Cuno-tigernos", which is composed of the elements *"cun", a hound, and *"tigerno", a lord, prince, or king. The evidence is based on the Old Welsh record "Conthigirn(i)". Other etymologies have been suggested, including British *"Kintu-tigernos" 'chief prince' based on the English form Kentigern, but the Old Welsh form above and Old English "Cundiʒeorn" do not appear to support this.
