Meaning & origin

Alexios is a name of ancient Greek origin, meaning "defender" or "helper." While it has a long history in the Byzantine Empire and modern Greece, its use in the United States is quite rare. According to Social Security data, the name first appeared in U.S. records in 1980, and as of 2023 it ranked 4,539th, with about 1 in 77,640 newborn boys receiving the name. Its peak popularity came in 2019, though it has since remained relatively stable in usage. The name is not strongly associated with any particular state, reflecting its scattered, infrequent appearance nationwide. Parents choosing Alexios often seek a classical Greek name with a strong, protective meaning and a distinguished historical pedigree.

Alexios is the ancient Greek form of Alexis, derived from the Greek verb "alexein" meaning "to defend" or "to help." It was a common name in the Byzantine Empire, borne by several emperors, and has been used in modern Greece and among the Greek diaspora.
