Ezio Mizzan (1905 – 26 March 1969) was an Italian diplomat. After graduating in law in Rome, Mizzan started his career at the Farnesina. He was sent as consul to Rio and Annaba, and acted as a diplomat in the Italian Embassies in Bucharest, Brussels, Berlin and Paris. In the middle of 1946 he was sent to China, where he was initially appointed consul of Hankou. Mizzan lived firsthand the advent of Communism in China, where he remained, as first secretary of the Italian embassy and the de facto leader of diplomatic relations, after the Italian ambassador fled to Italy in 1950. He played an important role in the bilateral relations between China and Italy.
