Alexey ('Aleksey) (Russian:Алексе́й, [ɐlʲɪkˈsʲej]) (Bulgarian:Алексей, [aleksej]) is a Russian and Bulgarian male first name deriving from the Greek Alexios (Αλέξιος), meaning "Defender", and thus of the same origin as the Latin Alexius.

Alexey may also be romanized as "Alexei", "Aleksei", "Aleksey", "Alexej", "Aleksej", etc. It has been commonly westernized as Alexis.
