The Calogerà family (Greek: Καλογερά (Kalogera or Kaloghera, from Kalogeros), Croatian: Kalogjera and Kalođera) are an ancient Byzantine-, and later Greco-Venetian, noble gens that has produced many important individuals in the history of Europe and Brazil. With origins in Cyprus and Byzantium, the family achieved levels of wealth, prominence, and aristocracy over the centuries in branches found across modern Greece, Italy, Croatia, Serbia, Albania, Romania, France, and Brazil. The Calogerà are studied in numerous registers of nobility, including the Libro d'Oro of Corfu, (1873), (1925), and (2000), among others. Members and descendants of this family continue to serve important roles in their respective countries to this day.
