Amintore Fanfani (; 6 February 1908 – 20 November 1999) was an Italian career politician and the 33rd man to serve the office of Prime Minister of the State. He was one of the well-known Italian politicians after the Second World War, and a historical figure of the Christian Democracy (Italian: Democrazia Cristiana – DC).
Fanfani and Giovanni Giolitti still hold the record as the only statesmen to have served as prime minister of Italy in five non-consecutive periods of office. Fanfani was one of the dominant figures of the Italian Christian Democrats for over three decades.
