Cadwallen is Welsh in Origin.

Cadwallen is a rare Anglicized variant of the Welsh name Cadwallon (Old Welsh Catguallon). It combines cad, meaning “battle,” with a second element related to gwallon/gwal(l)on, a leadership or prowess term cognate with the gwaladr in Cadwaladr. As a result, Cadwallen carries the sense “battle leader” or “leader in battle.” The -en ending reflects later English spellings rather than standard Welsh orthography. Closely related forms include Cadwallon and Cadwalon; the historically connected Cadwaladr shares the same first element and a near-identical meaning.

The name is best known from Cadwallon ap Cadfan, 7th‑century king of Gwynedd, remembered for his campaigns in Northumbria and for being the father of Cadwaladr. It appears in early sources such as Annales Cambriae and later Welsh chronicles. Usage declined after the medieval period, with occasional 19th‑century revivalist interest. Today Cadwallen/Cadwallon remains very uncommon, mostly encountered in Wales or among enthusiasts of Welsh heritage.
