Mario Traversoni (born 12 April 1972 in Codogno, Province of Lodi) is an Italian former professional road bicycle racer.
In Stage 19 of the 1997 Tour de France, Traversoni finished third, 26 seconds behind Bart Voskamp and Jens Heppner. However, both Voskamp and Heppner were disqualified for bumping shoulders some 50 yards from the finish. A surprised Traversoni was thus classified as the winner of the stage, which would be his only stage win in the Tour de France.
