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.

Duboc would end the 1911 Tour de France in second place, his best result.
