Giovanni Palatucci (31 May 1909 – 10 February 1945) was an Italian police official who was long believed to have saved thousands of Jews in Fiume between 1939 and 1944 (current Rijeka in Croatia) from being deported to Nazi extermination camps.
 In 2013 a research panel of historians led by the "Centro Primo Levi" reviewed almost 700 documents and concluded that Palatucci had followed RSI and German orders concerning the Jews and enabling the deportation of the majority of the 570 Jews living in Fiume and surrounding areas, 412 of whom were deported to Auschwitz, a higher percentage than in any Italian city.
