Victorio Codovilla, born Vittorio Codovilla, was an Italian-born Argentine socialist and later communist politician. At first a member of the Italian Socialist Party, he emigrated to Argentina in 1912 and went on to hold prominent posts in the Comintern and the Communist Party of Argentina (PCA), of which he was General Secretary in 1941–1963 and President in 1963–1970.

An International Meeting of Communist and Workers Parties was held in Moscow, Soviet Union, November 16–19, 1957. The meeting was attended by 64 political parties from all over the world. The meeting was the first of its kind, marking a new form of forum for the world communist movement following the disbanding of the Communist International (Comintern) and the Information Bureau of the Communist and Workers' Parties (Cominform). Four additional parties attended clandestinely out of fear of repercussions at home.
