Loredan () is a Venetian surname. The House of Loredan is an aristocratic Venetian family that included various doges of the Republic of Venice, and the surname is almost exclusively associated with the family. The surname most likely originated from the toponym Loreo (a town in the Veneto), which itself originated from its Latin name Lauretum, meaning laurel. Another theory of the origin of the surname, though most likely legendary, is that it comes from the Latin epithet Laureati, given to ancestors of the Loredan family due to their historical glory in ancient Rome and the many victories they achieved in battles. The surname is spelled Loredano () or Loredan in Italian, Lauredano or Lauredanus in Latin, and Lorentano () in Greek, though it is also historically found as Lordas () and Lordano (). The feminine name Loredana, common in Italy and Romania, was likely inspired by the surname.
