Gentullio Campagnolo (26 August 1901 – 3 February 1983) was an Italian racing cyclist and inventor who patented the quick release skewer, as well as founder of the bicycle component company Campagnolo.

Many professional cyclists have used Campagnolo components, including Fausto Coppi, Gino Bartali, Eddy Merckx (Merckx was a close friend of Campagnolo and became an iconic symbol of the company), Bernard Hinault, Greg LeMond, Miguel Indurain and Philippe Gilbert.
