The siege of Zadar (12 August 1345 – 21 December 1346) was a successful attempt of the Republic of Venice to capture Zadar (or Zara), a Croatian coastal city in northern Dalmatia. It was a combined land and sea offensive by the Venetians, consisting of many separate battles and operations against the citizens of Zadar, who refused to accept Venetian suzerainty and demanded autonomy. Despite receiving military aid from Croato-Hungarian king Louis the Angevin, Zadar was unable to resist the siege and was finally defeated.
