The 2014 Tour de France was the 101st edition of the race, one of cycling's Grand Tours. The 3,660.5-kilometre (2,274.5 mi) race included 21 stages, starting in Leeds, Yorkshire, United Kingdom, on 5 July and finishing on the Champs-Élysées in Paris on 27 July. The race also visited Belgium for part of a stage. Vincenzo Nibali of the Astana team won the overall general classification by more than seven minutes, the biggest winning margin since 1997. By winning, he had acquired victories in all Grand Tours. Jean-Christophe Péraud (Ag2r–La Mondiale) placed second, with Thibaut Pinot (FDJ.fr) third.

Marcel Kittel of Giant–Shimano was the first rider to wear the general classification leader's yellow jersey after winning stage one. He lost the following day to stage winner Nibali as the race reached the mountains. Nibali held the race lead until the end of the ninth stage, when it was taken by Lotto–Belisol's Tony Gallopin. The yellow jersey returned to Nibali the following stage, and he held it until the conclusion of the race.

The points classification was decided early in the race and was won by Cannondale's Peter Sagan. Rafał Majka of Tinkoff–Saxo, winner of two mountain stages, won the mountains classification. Pinot finished as the best young rider. The team classification was won by Ag2r–La Mondiale and Alessandro De Marchi (Cannondale) was given the award for the most combative rider. Kittel and Nibali won the most stages, with four each.

Following criticism by the professional women's peloton and campaign groups like Le Tour Entier regarding the lack of a women's Tour de France, a one day women's race – La Course by Le Tour de France – was held on the Champs-Élysées, prior to the last stage of the Tour.

Twenty-two teams participated in the 2014 edition of the Tour de France. The race was the 18th of the 29 events in the UCI World Tour, and all of its eighteen UCI ProTeams were automatically invited, and obliged, to attend the race. On 28 January 2014, the organiser of the Tour, Amaury Sport Organisation (ASO), announced the four second-tier UCI Professional Continental teams given wildcard invitations: Cofidis, Bretagne–Séché Environnement, IAM Cycling and NetApp–Endura. The team presentation – where the members of each team's roster are introduced in front of the media and local dignitaries – took place at the First Direct Arena in Leeds, United Kingdom, on 3 July, two days before the opening stage held in the city. The riders arrived at the arena by a ceremonial ride from the University of Leeds. The event included performances from Embrace and Opera North, in front of an audience of 10,000.

Each squad was allowed a maximum of nine riders, therefore the start list contained a total of 198 riders. Of these, 47 were riding the Tour de France for the first time. The riders came from 34 countries; France, Spain, Italy, Netherlands, Germany, Australia and Belgium all had 10 or more riders in the race. Giant–Shimano's Ji Cheng was the first Chinese rider to participate in the Tour. Riders from eight countries won stages during the race; German riders won the largest number of stages, with seven. The average age of riders in the race was 29.88 years, ranging from the 20-year-old Danny van Poppel to the 42-year-old Jens Voigt, both Trek Factory Racing riders. Voigt, riding in his final year as a professional, equalled Stuart O'Grady's record for most appearances in the Tour with 17. Garmin–Sharp had the highest average age, while Trek Factory Racing had the lowest.
