Lorenzo Bernucci is an Italian former professional road bicycle racer. He rose to international prominence when he won stage 6 of the 2005 Tour de France, when riding for Fassa Bortolo.

The 2005 Tour de France was the 92nd edition of the Tour de France, one of cycling's Grand Tours. It took place between 2–24 July, with 21 stages covering a distance 3,593 km (2,233 mi). It has no overall winner—although American cyclist Lance Armstrong originally won the event, the United States Anti-Doping Agency announced on 24 August 2012 that they had disqualified Armstrong from all his results since 1 August 1998, including his seven Tour de France wins from 1999 to 2005. The verdict was subsequently confirmed by the UCI.
