Carlo Fidanza (born 21 September 1976) is an Italian politician who has served as a Member of the European Parliament (MEP) since 2019, previously holding a seat from 2009 to 2014.

On 20 December 2012 he left the PDL and was one of the founders of Fratelli d'Italia, the party promoted by Giorgia Meloni, Ignazio La Russa and Guido Crosetto.

On 30 September 2021, Fanpage.it published an investigation revealing footage recorded with a hidden camera by an infiltrated journalist, in which Fidanza, together with the Milan district councillor Roberto Jonghi Lavarini, asked the journalist, who was pretending to be an entrepreneur, to finance Chiara Valcepina's election campaign in the 2021 Milan municipal election, saying they could pay under the table and launder that money.

The discussion led to jokes about Jews, black people, references to Adolf Hitler's speech during the Beer Hall Putsch, and Fidanza making the gesture of the Roman salute.

The investigation also involved Mauro Borghezio, a former MEP from the League (Lega) and the Lega regional councillor in Lombardy, Massimiliano Bastoni, and the Milan city councillor Silvia Sardone, who were filmed while proposing to make the third League with Lealtà Azione, a neo-Nazi movement, masquerading it as a non-profit organization to distribute parcels of pasta to voters with photos of the candidates on them.
