Cadwaladyr is Welsh in Origin.

Cadwaladyr is a rare Welsh form of Cadwaladr, built from cad “battle” and gwaladr “leader, prince,” yielding the sense “battle leader” or “ruler in war.” The -yr ending reflects an archaizing or dialectal spelling sometimes seen in older Welsh orthography, though Cadwaladr is the standard modern form.

The name was borne by Cadwaladr ap Cadwallon (7th century), last king of Gwynedd in early medieval tradition and later venerated as “the Blessed,” a figure tied to the prophetic Red Dragon of Wales. Usage persisted in medieval Wales, then waned, before modest revival during the 19th-century Welsh cultural renaissance. Anglicized variants include Cadwalader and Cadwallader (also common as surnames), with occasional Cadwaller; Welsh forms remain Cadwaladr/Cadwaladyr. Today it is extremely uncommon as a given name, chosen for its heroic, historic resonance and unmistakably Welsh identity.
