Oleksii is Ukrainian in Origin.

Oleksii is the standard Ukrainian form of Greek Alexios (Latin Alexius), derived from the verb alexein "to defend, to help," yielding the meaning "defender" or "helper." The name entered the Slavic world through Byzantine and Orthodox Christian influence; veneration of Saint Alexius, the "Man of God," and the reputation of Byzantine emperors named Alexios encouraged its adoption in Kyivan Rus' and later Ukrainian lands.

Common modern transliterations include Oleksiy and, less often, Olexiy; related forms abroad are Alexei/Aleksey (Russian), Aleksi (Finnish/Georgian), Alexios (Greek), Alexis (French/English), and Latin Alexius. Ukrainian nicknames include Lesyk and Les, with Russian-influenced Lyosha also recognized. The name remains popular in contemporary Ukraine, especially post-independence, as a marker of Ukrainian identity. Notable bearers include strongman Oleksii Novikov and politician Oleksii Reznikov.
