Arthus is Celtic in Origin.

Arthus is a French and Latinized variant of Arthur, closely related to the Old French form Artus used in medieval romances. Its etymology is debated: many scholars connect it to Celtic artos “bear,” yielding a sense like “bear-man” or “bear-hero,” while others trace it to the Roman family name Artorius, of uncertain (possibly Etruscan) origin. As a given name, Arthus preserves the learned -us ending that scribes applied in Latin chronicles and charters.

Usage appears sporadically in northern France and Brittany from the late Middle Ages onward, with literary prestige reinforced by the Arthurian cycle and a 19th‑century revival of medieval names. Today it remains rare but recognizable in Francophone regions, sometimes chosen as a distinctive twist on Arthur. Related forms include Arthur (English, French, German), Artus/Artús (Old French/Occitan), Artur (Polish, Portuguese), Arturo (Spanish, Italian), and Breton Arzhur.
