Alexander (/ˈæləɡzˈændər/, /ˈæləɡzˈɑːndər/) is a common male first name, and less common surname derived from the Greek "Αλέξανδρος" (Aléxandros). The most famous is Alexander the Great, who created one of the largest empires in ancient history.

The earliest attested form of the name is the Mycenaean Greek feminine anthroponym ...
