Meaning & origin
Arius is a rare but intriguing name with ancient Greek roots. Born by a controversial theologian, it has been in modest use in the U.S. since 1982. Its popularity peaked in 2021, though it has since seen a slight decline. The name is most common in Ohio, New York, and Texas, reflecting a scattered but dedicated following. With a distinctive sound and a connection to classical antiquity, Arius appeals to parents seeking a name that is both historic and uncommon.
Arius is a Latinized form of the Greek name Ἄρειος (Areios), derived from Ἄρης (Ares), the god of war. It was notably borne by a fourth-century Christian theologian from Alexandria whose teachings, known as Arianism, were condemned as heresy. The name has seen limited but consistent use in the English-speaking world since the late 20th century.
