The bombing of Zadar () during the Second World War by the Allies lasted from November 1943 to October 1944. Although other large cities in Italy were also bombed, the bombing of Zadar stands out because of the number of attacks and the number of fatalities. Reports vary greatly; the Allies documented 30 bombing raids, while contemporary Italian accounts claim 54. Fatalities recorded range from under 1,000, up to as many as 4,000 of the city's 20,000 inhabitants. It is the most significant historical event in Zadar after the Siege of Zadar in 1202 by forces of the Fourth Crusade.
