Paul Duboc (2 April 1884 – 19 August 1941) was a French professional road bicycle racer from 1907 through 1927. Despite winning 5 career stages in the Tour de France, he may be most remembered for being disqualified at the 1919 Tour de France for borrowing a car to go and repair his pedal axle. In 1911, Duboc was close to winning the Tour de France, when he became ill after drinking from a poisoned bottle given to him. His fans were blaming the classification leader Gustave Garrigou, and the Tour organizers advised Garrigou to ride under disguise. Duboc would end the 1911 Tour de France in second place, his best result.
