After winning the 6 Hours of Spa-Francorchamps, Toyota drivers Fernando Alonso, Sébastien Buemi and Kazuki Nakajima led the LMP Drivers' Championship with 160 points, 31 ahead of their teammates Mike Conway, Kamui Kobayashi and José María López in second.{{Cite web|url=https://www.fia.com/events/world-endurance-championship/season-2018/standings|title=Standings|publisher=Fédération Internationale de l'Automobile|archive-url=https://web.archive.org/web/20190711081539/https://www.fia.com/events/world-endurance-championship/season-2018/standings|archive-date=11 July 2019|url-status=live|access-date=11 July 2019}} 38 points were available for the final race, which meant Conway, Kobayashi and López could win the LMP Drivers' Championship if they won and Alonso, Buemi and Nakajima finished eighth or lower.{{Cite web|url=http://www.dailysportscar.com/2019/06/15/so-just-who-is-in-a-wec-title-hunt-going-into-le-mans.html|title=So Just Who Is in a WEC Title Hunt Going into Le Mans?|last=Goodwin|first=Graham|date=15 June 2019|publisher=DailySportsCar|archive-url=https://web.archive.org/web/20190819201221/http://www.dailysportscar.com/2019/06/15/so-just-who-is-in-a-wec-title-hunt-going-into-le-mans.html|archive-date=19 August 2019|url-status=live|access-date=19 August 2019}} With 140 points, Porsche's Michael Christensen and Kévin Estre led the GTE Drivers' Championship by 36 points over their second-placed teammates Gianmaria Bruni and Richard Lietz. Christensen and Estre needed to finish eighth or better to claim the title as Bruni and Lietz needed to win at Le Mans and their teammates to attain a sub-par result. The LMP1 Teams' Championship and the GTE Manufacturers' Championship had already been won by Toyota and Porsche, respectively.

Following a two-lap victory for Porsche in the Le Mans Grand Touring Professional (LMGTE Pro) category in {{24hLM|2018}}, the ACO revised Le Mans' safety implementation system after team managers raised procedural concerns. Full course yellow flags mandating cars to slow to {{Convert|80|km/h|mph|abbr=on}} in the event of an accident were implemented for the first time at Le Mans. The system became the preferred method of slowing the race as opposed to deploying three safety cars and enforcing slow zones. The ACO also permitted drivers to enter the pit lane during safety car conditions and exit it before a second safety car passed by so that they could remain in the same group of vehicles when racing resumed.{{Cite web|url=https://sportscar365.com/lemans/wec/aco-tweaks-approach-to-le-mans-safety-cars/|title=ACO Tweaks Le Mans Safety Car Procedure|last=Lloyd|first=Daniel|date=11 February 2019|publisher=SportsCar365|archive-url=https://web.archive.org/web/20190324110940/https://sportscar365.com/lemans/wec/aco-tweaks-approach-to-le-mans-safety-cars/|archive-date=24 March 2019|url-status=live|access-date=21 August 2019}}

The ACO Selection Committee received 75 applications for entries between the LMP1 (Le Mans Prototype 1), LMP2 (Le Mans Prototype 2), LMGTE Pro and LMGTE Am (Le Mans Grand Touring Amateur) categories from 20 December 2018 to 30 January 2019. The automotive group initially planned to accept 60 cars into the race but wishing to not exclude applications of a "high standard" they allowed 62 to race. The ten-panel Selection Committee took steps to ensure that the two additional required pits would be operational in time for the 2019 edition.{{Cite news|url=https://www.independent.co.uk/sport/motor-racing/le-mans-24-hours-schedule-entry-list-teams-drivers-how-to-watch-tv-channel-online-a8952211.html|title=Le Mans 2019: Schedule, full entry list, driver line-up and how to watch on TV and online for 24-hour race|last=de Menzes|first=Jack|date=15 June 2019|work=The Independent|access-date=20 August 2019|archive-url=https://web.archive.org/web/20190614180733/https://www.independent.co.uk/sport/motor-racing/le-mans-24-hours-schedule-entry-list-teams-drivers-how-to-watch-tv-channel-online-a8952211.html|archive-date=14 June 2019|url-status=live}}{{Cite web|url=https://www.endurance-info.com/fr/comment-deposer-un-dossier-dengagement-aux-24-heures-du-mans/|title=Comment déposer un dossier d'engagement aux 24 Heures du Mans ?|last=Mercier|first=Laurent|date=25 December 2018|publisher=Endurance-Info|language=fr|archive-url=https://web.archive.org/web/20190820083728/https://www.endurance-info.com/fr/comment-deposer-un-dossier-dengagement-aux-24-heures-du-mans/|archive-date=20 August 2019|url-status=live|access-date=20 August 2019}}

Automatic entry invitations were earned by teams that won their class in the 2018 24 Hours of Le Mans. Teams who won championships in the European Le Mans Series (ELMS), Asian Le Mans Series (ALMS), and the Michelin Le Mans Cup (MLMC) were also invited. The second-place finisher in the 2018 ELMS LMGTE championship also earned an automatic invitation. The ACO chose two IMSA SportsCar Championship (IMSA) teams to be automatic entries regardless of their performance or category. As invitations were granted to teams, they were allowed to change their cars from the previous year to the next, but not their category. The LMGTE class invitations from the ELMS and ALMS were allowed to choose between the Pro and Am categories. ELMS' 2018 LMP3 (Le Mans Prototype 3) champion was required to field an entry in LMP2 while the 2018–19 ALMS LMP3 champion was permitted to choose between LMP2 or LMGTE Am. The 2018 MLMC GT3 champion was limited to the LMGTE Am category.{{Cite web|url=http://www.dailysportscar.com/2018/11/02/the-2019-le-mans-24-hours-whos-already-on-the-list.html|title=The 2019 Le Mans 24 Hours: Who's Already On The List?|last=Goodwin|first=Graham|date=2 November 2018|publisher=DailySportsCar|archive-url=https://web.archive.org/web/20190626074007/http://www.dailysportscar.com/2018/11/02/the-2019-le-mans-24-hours-whos-already-on-the-list.html|archive-date=26 June 2019|url-status=live|access-date=20 August 2019}}{{Cite web|url=https://sportscar365.com/lemans/wec/four-more-teams-gain-24h-le-mans-auto-invites/|title=Four Asian LMS Teams Gain Le Mans Auto Invites|last=Lloyd|first=Daniel|date=25 February 2019|publisher=SportsCar365|archive-url=https://web.archive.org/web/20190820083727/https://sportscar365.com/lemans/wec/four-more-teams-gain-24h-le-mans-auto-invites/|archive-date=20 August 2019|url-status=live|access-date=20 August 2019}}

For the 2019 event, the list of race entries was revealed in two stages: the first 42 cars were announced on 11 February with the rest of the field and 10 reserve cars in the LMP2 class and the two LMGTE categories announced on 1 March. The ACO attributed the 2018–19 FIA WEC's format as a reason for the alteration.{{Cite web|url=https://www.autosport.com/wec/news/140430/2019-le-mans-entry-list-set-for-split-reveal|title=Le Mans 24 Hours 2019 entry list to be revealed in two stages|last=Watkins|first=Gary|date=29 November 2018|website=Autosport|archive-url=https://web.archive.org/web/20190820083723/https://www.autosport.com/wec/news/140430/2019-le-mans-entry-list-set-for-split-reveal|archive-date=20 August 2019|url-status=live|access-date=20 August 2019}} In addition from the 34 guaranteed entries from the FIA WEC, 15 came from the ELMS, nine from IMSA, five from the ALMS and a solitary one-off Le Mans specific entry.{{Cite web|url=http://fiawec.alkamelsystems.com/Results/08_2018-2019/08_LE%20MANS/Event%20Info/Entry%20list.pdf|title=List of the competitors, drivers and cars eligible to take part in the official practice sessions: 10.06.2019|date=10 June 2019|publisher=Automobile Club de l'Ouest|access-date=20 August 2019}}

After the safety cars were withdrawn, Ben Keating's Ford ran into a gravel trap at the first Mulsanne Straight chicane, from which he escaped without damage to the car and retained the lead of LMGTE Am. Menezes' No. 3 Rebellion car incurred a three-minute stop-and-go penalty for a procedural error on the team's usage of tyre compounds, promoting Vandoorne's No. 11 SMP car to third overall. Just after Menezes rejoined the race, he spun into a gravel trap in the Porsche Curves and returned to the garage after vehicular assistance. 17 hours and 25 minutes in, Tung's No. 38 Jackie Chan car slowed with a puncture and returned to the pit lane to retain third position in LMP2 from François Perrodo's No. 28 TDS car.

It just neutralizes the race and then you end up with this huge separation. For the second year in a row, it's kind of taken away the spectacle at the end." Lietz stated his belief that all of the safety car periods were correctly deployed for safety reasons. The Corvette Racing team manager, Ben Johnson, said he was unsure why some safety car periods were deployed in lieu of full course yellow flags to slow the race and called for clarity on when to use the procedure.

Alonso, Buemi and Nakajima took the LMP Drivers' Championship with 198 points. They were 41 points ahead of their teammates Conway, Kobayashi and López in second position. Laurent and Menezes followed in third place with 114 points, ahead of Aleshin and Petrov in fourth with 94 points and Neel Jani and Lotterer in fifth with 91 points. With 155 points, Estre and Christensen won the GTE Drivers' Championship, 18{{1/2}} ahead of Calado and Pier Guidi in second. Bruni and Lietz followed in third position with 131 points and Tincknell and Priaulx were fourth with 90 points.

The minimum number of laps for classification (70 per cent of the overall winning car's race distance) was 270 laps. Class winners are in bold.
