Eleutherius is Greek in Origin.

Eleutherius is the Latinized form of Greek Eleutherios (Eleutherios), from eleutheros “free,” yielding the sense “the liberator” or “belonging to freedom.” The name circulated in the Hellenistic and early Christian world and carries a virtue-meaning akin to Latin Liberius.

Borne by several early saints and martyrs - including a 2nd-century bishop venerated as Saint Eleutherius - and by Pope Eleutherius (c. 174–189), it entered Western martyrologies and remained familiar in ecclesiastical contexts though uncommon as a lay given name. The form persists in Orthodox lands as Eleftherios, with the everyday Greek nickname Lefteris; feminine counterparts include Eleftheria/Eleutheria. Romance-language variants are Eleuterio (Italian, Spanish, Portuguese) and Eleuteria for women; French has Éleuthère, and Romanian uses Elefterie. English typically preserves the scholarly Eleutherius, now rare and antiquarian, favored in religious orders or by parents seeking a distinctive classical-Christian heritage.
