Gaetano Belloni (26 August 1892 – 9 January 1980) was an Italian professional road racing cyclist. The highlights of his career were his overall win in the 1920 Giro d'Italia, the two victories in Milan–San Remo (1917 and 1920), and the three victories in the Giro di Lombardia (1915, 1918 and 1928). Belloni was born at Pizzighettone, near Cremona, and made his debut in the road cycling world in the wake of his elder brother Amleto. As an amateur, in 1914 he won the "Small" Giro di Lombardia and the Coppa del Re, as well as the Italian championship.
