Oscar Fulvio Giannino (born 1 September 1961) is an Italian journalist and politician.

A member of the Liberal Democratic Alliance for Italy (Italian: Alleanza Liberaldemocratica per l'Italia, ALI) since 2013, he is the former president of the free-market-oriented Stop the Decline (Italian: Fermare il Declino, FiD) party.

[1][2] In August 2012, Giannino founded the Stop the Decline party, and in December he announced that he would run to become Prime Minister of Italy (Italian: presidente del Consiglio dei ministri) for the 2013 Italian general election.

He stepped down from FiD's presidency (Italian: capo della forza politica) after it was discovered that he had fabricated his résumé by adding false academic claims, such as a law degree in Italy and a master's degree in corporate finance and public finance at the University of Chicago Booth School of Business.

[3] The deception was discovered by the party co-founder and Giannino's colleague, Luigi Zingales, who was professor at the Booth School of Business and left the political association.
