The 2001 Tour de France was a multiple stage bicycle race held from 7 July to 29 July 2001, and the 88th edition of the Tour de France. It has no overall winner—although American cyclist Lance Armstrong originally won the event, the United States Anti-Doping Agency announced in August 2012 that they had disqualified Armstrong from all his results since 1998, including his seven Tour de France wins from 1999–2005. The verdict was subsequently confirmed by the Union Cycliste Internationale.

The race included a 67-km long team time trial, two individual time trials and five consecutive mountain-top finishing stages, the second of which was the Chamrousse special category climb time trial. Thus, all the high-mountain stages were grouped consecutively, following the climbing time trial, with one rest day in between. France was ridden 'clockwise', so the Alps were visited before the Pyrenees. The Tour started in France but also visited Belgium in its first week. The ceremonial final stage finished at the Champs-Élysées in Paris, as is tradition. Erik Zabel won his record sixth consecutive points classification victory.
