The 2009 24 Hours of Le Mans () was the 77th Grand Prix of Endurance, an endurance auto race run over 24 hours.

1. Due to Audi Sport North America already earning two entries (first in previous 24 Hours of Le Mans and first at Petit Le Mans), they could not receive the automatic invitation for also winning the American Le Mans Series championship.

Applications Prior to the deadline for applications, 82 separate entries by teams representing 17 countries were received by the ACO. This amount is only six less than the total of applications received for the previous running of the 24 Hours of Le Mans. The ACO Selection Committee decided on which teams were invited to fill the remaining 40 positions alongside those teams who had already received automatic invitations, along with ten reserve entries.

Entry list On 26 February, the ACO announced their list of 55 entries which will be invited to take part in the 2009 24 Hours of Le Mans. 21 cars within the LMP1 category include Audi, Peugeot, and Aston Martin with three cars each, as well as private entries for the Kolles Audis, Pescarolo Peugeot, and Speedy-Sebah Aston Martin. This also made a total of nine cars which would be using diesel fuel. LMP2 featured previous race winners Team Goh in a previous winning car, the Porsche RS Spyder, joined by last year's runner-up Team Essex. Mazda supplied engines for four entries, split amongst the Lola and Pescarolo chassis.

The GT1 category was fought amongst three manufacturers, as Corvette Racing and Luc Alphand Aventures attempted to overcome the two private Aston Martin and Lamborghini entries. GT2 was once again dominated by the Ferrari and Porsche battle, although Ferrari had the power of numbers with its ten entries compared to Porsche's five. Sole entries from Spyker and the Drayson Aston Martin completed the GT2 field.

Reserve entries Ten entries are granted a reserve entry, in case an entry from the list of 55 withdraws prior to the event. These ten entries will be allowed to join the race entry list in the order they are listed here, regardless of their class.

On 31 March, Gigawave Motorsport withdrew their Aston Martin from the GT1 category of the entry list in order to concentrate on their development of the Nissan GT-R program. This promoted Advanced Engineering/Team Seattle from the reserve list to the entry list. Three days later Epsilon Euskadi withdrew their LMP1 entry which was replaced by the Endurance China Team. Epsilon Euskadi also withdrew their second entry from the reserve list. On 29 April, it was announced that Vitaphone Racing withdrew their LMP2 entry and was replaced by a second IMSA Performance Matmut GT2 entry. Racing Box also announced that they withdrew their LMP2 reserve entry. IPB Spartak Racing announced their withdrawal from the event on 15 May because one of their drivers, Peter Kox, was unable to participate in the race. It was replaced by the Barazi-Epsilon LMP2 entry.

On 22 May, reserve entries were no longer able to be accepted into the race, regardless of further withdrawals. The entries of Gerard Welter's WR-Zytek LMP2, Team Felbermayr-Proton's Porsche GT2, Snoras Spyker Squadron's Spyker GT2, and Larbre Compétition's Saleen GT1 were the only remaining reserves at the time of the entry list closure.

Free practice After the cancellation of the test session, Wednesday's schedule was changed from a qualifying session to a six-hour free practice. Track conditions varied as rain arrived several times during the practice, limiting the amount of time available with a dry circuit. Audi led the session with Allan McNish setting a fastest lap of 3:30.708 in the No. 1 car, followed immediately by the No. 2 Audi. The best Peugeot was the No. 9 car, followed immediately by the privately entered Pescarolo Sport Peugeot. The fastest LMP1 not running a diesel engine was the second Pescarolo entry with a time of 3:35.868, followed by the No. 008 and No. 007 Aston Martins.

The LMP2 category was led by the Porsche RS Spyders, with Team Essex's 3:46.426 ahead of the Navi Team Goh entry. Quifel ASM Team's Ginetta-Zytek was a distant third, ten seconds behind Team Essex. Corvette Racing were at the front of GT1, with the No. 63's 3:57.876 lap time ahead of the No. 64 car. Jetalliance Racing were third while the two Luc Alphand Corvettes did few laps after fixing an incorrectly installed rollcage and the JLOC Lamborghini did not complete a lap after breaking a driveshaft. Porsche were ahead of Ferrari in the GT2 category, with Felbermayr-Proton ahead of the Risi Competizione. Spyker Squadron were able to reach third in the class.

The only major incident of the practice session was an accident by KSM's driver Jean de Pourtales. The driver spun approaching the Dunlop Chicane, impacting a concrete barrier before sliding into a tire barrier. The second impact ripped much of the rear of the car off.

Qualifying Stéphane Sarrazin claimed his third consecutive pole position at Le Mans, planting the No. 8 Peugeot at the front of the field with a lap time of 3:22.888. He set the lap on the third of his flying laps during a run near the end of the four-hour qualifying session, bettering Allan McNish's lap time by 0.8 seconds. McNish's lap was set on the final lap of the first two-hour qualifying session, beating the Peugeot of Franck Montagny who led much of the first session. McNish's lap remained at the top of the charts for much of the second session until Sarrazin's performance. Peugeot planned to practice race setups during the entire qualifying session, and were not seeking to obtain the pole position.

At the end of qualifying Peugeots filled the next three places on the grid behind the front row with the car of Pescarolo Sport settling in at fourth fastest. Aston Martin were able to secure the fastest lap for a petrol-powered car, with the No. 007 entry on a few thousandths of a second behind the No. 3 Audi and followed by the No. 008 Aston Martin and No. 13 Speedy Racing Team Sebah Aston Martin.

The Porsche RS Spyders continued their dominance in the LMP2 category, with Casper Elgaard of Team Essex ahead of Team Goh with a lap time of 3:37.720. Third in the category was the No. 33 Speedy Racing Team Sebah Lola-Judd which was over three seconds behind the Porsches. Corvette Racing secured the front row in the GT1 category, with Jan Magnussen's No. 63 entry half a second ahead of the No. 64 sister car. Jetalliance Racing's privately entered Aston Martin was under two seconds behind, and followed immediately by the two Luc Alphand Corvettes. The JLOC Lamborghini struggled with mechanical issues and was never able to lift itself from last place on grid.

The GT2 category was led by Porsche who bested their rivals Ferrari with two cars. Pole winner Flying Lizard Motorsports' 4:03.202 was less than a tenth of a second ahead of the No. 77 Felbermayr-Proton car. Risi Competizione led the Ferrari fight with a third place qualifying time, joined by JMB Racing and BMS Scuderia Italia. The Aston Martin of Drayson Racing was ninth in the category, while the Spyker was eleventh.

Several incidents occurred during the qualifying session. The Pescarolo Peugeot drive by Jean-Christophe Boullion spun at the Tetre Rouge corner and ripped the left front fender off the car after impacting the wall. The Peugeot was able to return to the pits and be repaired. The No. 007 Aston Martin also hit a wall after losing control during braking for the second chicane on the Mulsanne Straight.
