Aleksander is the Polish, Norwegian and Danish spelling of Alexander, from the Greek Alexandros, which means "defender of men", from alexein, to defend, and aner, man. The k spelling is a way for families with Polish or Scandinavian roots to honor that heritage while keeping a name everyone knows. In the United States Aleksander ranked number 1542 in 2000, peaked at number 1103 in 2009 and stands at number 1425 in 2025.
