Giorgio Napolitano was an Italian politician who served as the 11th President of Italy from 2006 to 2015, the first to be re-elected to the office. In office for 8 years and 244 days, he was the longest-serving president, until the record was surpassed by Sergio Mattarella in 2023. He also was the longest-lived president in the history of the Italian Republic, which has been in existence since 1946. Although he was a prominent figure of the First Italian Republic, he did not take part in the Constituent Assembly of Italy that drafted the Italian constitution; he is considered one of the symbols of the Second Italian Republic, which came about after the Tangentopoli scandal of the 1990s. Due to his dominant position in Italian politics, some critics have sometimes referred to him as Re Giorgio.

The president of Italy, officially titled President of the Italian Republic, is the head of state of Italy. In that role, the president represents national unity, and guarantees that Italian politics comply with the Constitution. The president is the commander-in-chief of the Italian Armed Forces and chairs the High Council of the Judiciary. A president's term of office lasts for seven years. The incumbent president is former constitutional judge Sergio Mattarella, who was elected on 31 January 2015, and re-elected on 29 January 2022.
