Cadwaladr, Cadwalader, or Cadwallader is a given name and surname of Welsh origin. It was most notably held by Cadwaladr, a seventh century king of Gwynedd, who was the last Welsh king to claim lordship over all of Britain.
The name is pronounced [kadˈwaladər] in Welsh and typically /kədˈwɒlədər/ in English. The spelling variant Cadwallader does not represent the pronunciation [kadˈwaɬadər], in spite of the double l, which usually represents a voiceless lateral fricative in Welsh (see Welsh orthography).
