Alexey is a Russian male given name, an alternate transcription of the Russian Алексей (see Aleksey). It ultimately derives from the Greek Alexios, meaning "defender", making it cognate with the Latin Alexius. The name is borne by several saints and historical figures, and remains widely used in Russia and other Slavic countries.EtymologyThe name Alexey traces its roots back to the ancient Greek name Alexios, derived from alexo meaning "to defend" or "to help". This connects it to the broader alexo root, which also appears in the names Alexis and Alexander. The Russian form Aleksei was adopted via the Byzantine Empire and Christianized through veneration of Eastern Orthodox saints.History and Royal BearersThe name gained prominence in Russia through Tsar Alexis of Russia (1629–1676), the second Romanov tsar, after whom the name became popular among the nobility and commoners. Saint Alexis, Metropolitan of Moscow, a 14th-century religious leader also contributed to its spread. In modern times, the name has been borne by figures such as cosmonaut Alexey Leonov (the first person to walk in space) and writer Alexey Tolstoy.Notable PeopleAlexey Leonov (1934–2019): Soviet cosmonaut who performed the first spacewalk in 1965.Alexey Miller (born 1962): CEO of Gazprom, Russian energy executive.Alexey Balabanov (1959–2013): Russian film director known for Brother and Brother 2.Variants and DiminutivesThe name has many variants across languages: Aleksey, Alexei, Aleksei.
