Jens Voigt (German: [jɛns foːkt]) (born 17 September 1971) is a German former professional road bicycle racer for several teams, the last one being UCI ProTeam Trek Factory Racing. Voigt wore the yellow jersey of the Tour de France twice, though he was never a contender for the overall title owing to the mountainous nature of the stages of the race being better suited to climbing specialists. His career achievements include winning the Critérium International a record-tying 5 times and a number of one-week stage races, as well as two Tour de France stage victories. In September 2014, he set a new hour record. The record was beaten by Matthias Brändle in October of the same year.

Voigt was as a rider generally popular with cycling fans, both for his aggressive riding style and his affable, forthright and articulate manners in dealing with the public and media. He speaks fluent French and English, in addition to his native German.
