The prime minister of Italy is the head of the Council of Ministers, which holds effective executive power in the Italian government. The first officeholder was Camillo Benso, Count of Cavour, who was sworn in on 23 March 1861 after the unification of Italy. Cavour previously served as prime minister of the Kingdom of Sardinia, an office from which the Italian prime minister took most of its powers and duties. During the era of the monarchy of Italy under the House of Savoy, prime ministers were appointed by the King of Italy, as laid down in the Albertine Statute (1848). From 1925 until the fall of the Fascist regime in Italy in 1943, the Italian fascist dictator Benito Mussolini formally modified the office title to "Head of Government, Prime Minister, Secretary of State". From 1861 to 1946, 30 men served as prime ministers, leading 67 governments in total.

After the abolition of the Kingdom of Italy in 1946 and the proclamation of the Italian Republic, the office was established by Articles 92 through 96 of the Constitution of Italy (1948). Alcide De Gasperi is the only prime minister who held this position both in the Kingdom of Italy and in the Italian Republic; he was in office for over seven consecutive years between 1945 and 1953, more than any other democratically-elected prime minister. The prime minister is appointed by the president of the Italian Republic and must receive a confidence vote by both houses of the Italian Parliament: the Chamber of Deputies and the Senate of the Republic. From 1946 to 2022, in the first 76 years after the creation of the Italian Republic, 30 men served as prime ministers. The incumbent officeholder is Giorgia Meloni, who was appointed on 22 October 2022, becoming the first woman to hold this office.

The longest-serving prime minister in the history of Italy was Mussolini, who ruled the country as Fascist Italy from 1922 until 1943; the longest-serving prime minister of the Italian Republic was Silvio Berlusconi, who held the position for more than nine years between 1994 and 2011. The shortest-serving officeholder was Tommaso Tittoni, who served as prime minister for 16 days in 1905, while the shortest-serving prime minister of the Italian Republic was Fernando Tambroni, who governed for 123 days in 1960.
