Elladio or Eladio is an Italian given name, also known in its feminine variants of Elladia or Eladia. It also appears in Latin as Helladius,[1][2] in Polish as Heladiusz or Eladiusz and in Spanish as Eladio.[2] These all derive from Ἑλλάδιος Helladios,[2] an ethnonymic name in Greek attested since late antiquity[3] and meaning 'one from Hellas' (i.e. from Greece; MASC).[4][5] This is similar to the name "Greca" (see names of Greece and names of the Greeks).
