Andreu (Eastern Calatan: [ənˈdɾew]) is a common Catalan, Spanish (Castilian), German and southern French given name of Ancient Greek origin, which also appears as a surname. The word Andreu is derived etymologically from the ancient Greek vocabulary word andros, the genitive of aner ("man") and so means "of the man". Thus, the name Andreu takes the meaning the one who is "manly", "strong", "courageous" or a "warrior". The contemporary Greek equivalent of the name is Andreou; the English equivalent is Andrew.
