Giuseppe Fietta (6 November 1883 – 1 October 1960) was an Italian prelate of the Catholic Church who worked in the diplomatic service of the Holy See from 1924 to 1958, including a stint as Apostolic Nuncio to Argentina from 1936 to 1953.

Born in Ivrea, Piedmont, Giuseppe Fietta studied at the Pontifical Gregorian University in Rome and was ordained to the priesthood on 4 November 1906.

On 30 March 1926 Pope Pius XI appointed Fietta Titular Archbishop of Serdica and, on 8 July, Apostolic Internuncio to Central America.
