Giulio Ramponi (8 January 1902 – December 1986) was an Italian automobile technician and racing driver. He was born in Milan where he worked for the Florentia car maker and the Pelizzola maker of fuel pumps. In 1918 he became the mechanic of his stepfathers friend, opera singer Giuseppe Campari (1892–1933) who won at Mugello in 1920 with Alfa Romeo. In 1924, Ramponi became chief riding mechanic and co-driver for Antonio Ascari (1888–1925) and his Alfa Romeo P2, in which Ascari was killed in 1925. Ramponi was not in the car, since a GP rule change in 1925 eliminated the use of riding mechanics. Ascari died in his arms.
