Georgios Averof (Greek: Θ/Κ Γεώργιος Αβέρωφ) is a Greek warship which served as the flagship of the Royal Hellenic Navy during most of the first half of the 20th Century. Although popularly known as a battleship (θωρηκτό), it is in fact an armored cruiser, (θωρακισμένο καταδρομικό), the only ship of this type still in existence.
