The RSI Police Order No. 5 (Italian: Ordinanza di polizia RSI n.5) was an order issued on 30 November 1943 in the Italian Social Republic (Italian: Repubblica Sociale Italiana, the RSI) to the Italian police in German-occupied northern Italy to arrest all Jews except those born of mixed marriages, which were required to be monitored by the police.
The order marked the final change of attitude of Fascist Italy towards the Jewish minority in the country, having gone from allowing active participation in the Fascist movement to the, official, start of discrimination with the Italian Racial Laws of 1938, to declaring them as of "enemy nationality" at the Congress of Verona in early November 1943 and, ultimately, to arrest and deportation to extermination camps with the Police Order No. 5 at the end of November.
The impact of the order can be judged by the fact that approximately half of the Jews arrested in Italy during the Holocaust were arrest by Italian police and the fact that Fascist Italy opened a number of concentration camps for arrested Jews immediately following the issue of the police order.
