The 1989 Tour de France was the 76th edition of the Tour de France, one of cycling's Grand Tours. The race consisted of 21 stages and a prologue, over 3,285 km (2,041 mi). It started on 1 July 1989 in Luxembourg before taking an anti-clockwise route through France to finish in Paris on 23 July. The race was won by Greg LeMond of the AD Renting–W-Cup–Bottecchia team. It was the second overall victory for the American, who had spent the previous two seasons recovering from a near-fatal hunting accident. In second place was previous two-time Tour winner Laurent Fignon (Super U–Raleigh–Fiat), ahead of Pedro Delgado (Reynolds), the defending champion.

Delgado started the race as the favourite, but lost almost three minutes on his principal rivals when he missed his start time in the prologue individual time trial. The race turned out to be a two-man battle between LeMond and Fignon, with the pair exchanging the race leader's yellow jersey several times. Fignon managed to match LeMond in the prologue, but in the other three individual time trials he lost time to LeMond, who took advantage of aerodynamic elbow-rest handlebars formerly used in triathlon events. Delgado launched several attacks in the mountain stages to eventually finish third, while LeMond rode defensively to preserve his chances. Fignon rode well in the mountains, including a strong performance at Alpe d'Huez which gave him the race lead on stage 17.

In the closest Tour in history, LeMond was trailing Fignon by fifty seconds at the start of the final stage, an individual time trial into Paris. LeMond was not expected to be able to make up this deficit, but he completed the 24.5 km (15.2 mi) stage at an average speed of 54.545 km/h (33.893 mph), the fastest individual time trial ever ridden in the Tour de France up to that point, and won the stage. Fignon's time was fifty-eight seconds slower than LeMond's, costing him the victory and giving LeMond his second Tour title by a margin of only eight seconds. From stage 5 onward, LeMond and Fignon were the only two men to lead the race. The two riders were never separated by more than fifty-three seconds throughout the event. Owing to its competitive nature, the 1989 Tour is often ranked among the best in the race's history.

The PDM–Ultima–Concorde team was the winner of the team classification and had four cyclists in the top ten of the general classification. They also won four of the five secondary individual classifications: Sean Kelly won both the points and intermediate sprints classifications, Gert-Jan Theunisse won the mountains classification and Steven Rooks won the combination classification. The young rider classification was won by Fabrice Philipot from the Toshiba team.

The 1989 Tour had a starting field of twenty-two teams of nine cyclists. Prior to 1989, the Société du Tour de France, organisers of the Tour, chose freely which teams they invited to the event. For 1989, the sport's governing body, the Fédération Internationale de Cyclisme Professionnel (FICP), demanded that the highest-ranked teams in the FICP Road World Rankings would receive an automatic invitation. The Tour organisers relented in exchange for being allowed to run the race over 23 days instead of the original 21-day period given by the FICP.

Eighteen teams received their invitations through the FICP rankings, while the organisers allocated four teams with wild cards. The Ariostea team would have been eligible to start through their ranking, but decided against competing. This allowed Greg LeMond's AD Renting–W-Cup–Bottecchia team to enter the race. The wild cards were given out to the teams of Kelme, Café de Colombia, Fagor–MBK, and 7-Eleven. Not invited was the Teka team, which failed to accumulate enough points in the World Rankings after Reimund Dietzen had to leave the 1989 Vuelta a España following a career-ending crash. Of the 198 cyclists starting the race, 39 were riding the Tour de France for the first time. The youngest rider was Juan Carlos Jusdado (BH), who was 22 years and 205 days old on the day of the prologue; the oldest, at 36 years and 139 days, was Helmut Wechselberger (Paternina).
