Meaning & origin

Alexius is a name with ancient Greek roots, derived from Alexios, meaning "defender." While related to the more common Alexis, Alexius has maintained a distinct, albeit rare, presence in the United States. First recorded in 1978, it saw its peak popularity in 1998, though it has never cracked the top 1,000. The name's trajectory has been falling since 1997, reflecting a gradual decline in usage. Despite its rarity, Alexius carries a strong historical resonance, having been borne by Byzantine emperors and saints.

Alexius is a Latinized form of the Greek name Alexios, derived from "alexein," meaning "to defend" or "to help." It was borne by several Byzantine emperors and saints, including Saint Alexius of Rome. The name gained popularity in medieval Europe and has seen occasional use in the English-speaking world, often as a variant of Alexis.
