Luigi Cacciatore (1900–1951) was an Italian socialist politician who served as the minister of posts and communications in 1947. He was a member and one of the leaders of the Italian Socialist Party.
Cacciatore was born in Mercato San Severino, near Salerno, on 26 July 1900.[1] From 1922 he worked in the building trade unions.[1] In 1925 he was arrested by the Fascist regime due to his activities.[1] After the end of the Fascist rule he involved in politics.[1] In the first meeting of the Italian Socialist Party of Proletarian Unity in Naples on 20 December 1943 he was elected to its National Council representing the province of Salerno.[1] He was appointed minister of posts and communications to the third cabinet of Prime Minister Alcide De Gasperi in 1947.[2] Then Cacciatore joined the Italian Socialist Party.[1] He was elected to the Italian Parliament from Benevento and represented the party at the parliament between 1 June 1948 to 17 August 1951. He died in Rome on 17 August 1951.[3] Spencer M. Di Scala argues that the death of Cacciatore weakened the Italian Socialist Party.[4]
