Apollonarius is Latin in Origin.

Apollonarius comes from Greek Apollōnários (Ἀπολλωνάριος), an adjective meaning “of Apollo” or “belonging to Apollo,” referencing the god of light, music, and prophecy. In Latin and ecclesiastical sources it appears as Apollinarius or Apollinaris; the Greek form Apollonarios is also found. Noted variants include French Apollinaire, Italian Apollinare, Spanish/Filipino Apolinario, Polish Apolinary, and Russian Apollinariy; feminine forms Apollinaria/Apolinariya and Apolinaria.

Attested in Hellenistic and Roman inscriptions and papyri, the name later passed into Christian usage, often reinterpreted despite its pagan root. Bearers include Saint Apollinaris of Ravenna, an early bishop-martyr, and Apollinarius of Laodicea, a 4th‑century theologian tied to “Apollinarianism.” Its saintly prestige kept it current in late antiquity and medieval calendars across Italy, Gaul, and the Orthodox East, though it remains rare in modern English. Related: Apollonius/Apollonios.
