The French Grand Prix (French: Grand Prix de France), formerly known as the Grand Prix de l'ACF (Automobile Club de France), was an auto race held as part of the Fédération Internationale de l'Automobile's annual Formula One World Championship. It was one of the oldest motor races in the world as well as the first "Grand Prix". It ceased, shortly after its centenary, in 2008 with 86 races having been held, due to unfavourable financial circumstances and venues. The race returned to the Formula One calendar in 2018 with Circuit Paul Ricard hosting the race, but was removed again after 2022.

Unusually even for a race of such longevity, the location of the Grand Prix has moved frequently with 16 different venues having been used over its life, a number only eclipsed by the 23 venues used for the Australian Grand Prix since its 1928 start. It is also one of four races (along with the Belgian, Italian and Spanish Grands Prix) to have been held as part of the three distinct Grand Prix championships (the World Manufacturers' Championship in the late 1920s, the European Championship in the 1930s and the Formula One World Championship since 1950).

The Grand Prix de l'ACF was tremendously influential in the early years of Grand Prix racing, leading the establishment of the rules and regulations of racing as well as setting trends in the evolution of racing. The power of the original organiser, the Automobile Club de France, established France as the home of motor racing organisation.

France was one of the first countries to hold motor racing events of any kind. The first competitive motor race, the Paris to Rouen Horseless Carriages Contest was held on 22 July 1894, and was organized by the Automobile Club de France (ACF). The race was 126 km (78 mi) long and was won by Count Jules-Albert de Dion in his De Dion Bouton steam powered car in just under 7 hours. This race was followed by races starting in Paris to various towns and cities around France such as Bordeaux, Marseille, Lyon and Dieppe, and also to various other European cities such as Amsterdam, Berlin, Innsbruck and Vienna. The 1901 Paris-Berlin race was noteworthy as the race winner, Henri Fournier averaged an astonishing 57 mph (93 km/h) in his Mors, but there were details of other incidents. A competitor driving a 40H.P. Panhard suddenly found the road blocked by a tram in the village of Metternich, and he deliberately ran into the vehicle to avoid the crowd of spectators. The tram was knocked off the rails; the car was hardly damaged. And in Reims, a future location of many French Grands Prix, another competitor in a Mors hit and killed a child who wandered onto the road.

But these races, held on public dirt roads that were not all closed to the public came to a halt in 1903. The Paris-Madrid race, a 1,307 km (812 mi) long competition from the French capital to the Spanish capital held in May of that year had over 300 entrants. Some of the cars were doing 140 km/h (87 mph)- an astonishingly fast speed for the time- not even rail locomotives were capable of hitting these speeds. It was not known at the time how safe these races would be or how these cars- made mostly of wood would perform, and development of the car had improved significantly over 9 years. The race was a disaster, with 8 people killed and over 15 injured in multiple accidents- and all of this happened before any of the competitors reached the Spanish border. Crowds of onlookers would stand right on the edge of the track, and children were wandering into the roads which became very dusty, and visibility was limited at best. The most notable fatality of this race was one Marcel Renault, one of the 3 brothers who founded the Renault car company, a manufacturer that would go on to have lots of success in Grand Prix racing many decades later and be a huge influence on French motorsport. When Renault reached the village of Payré just south of Grand Poitiers he lost control of his 16HP Renault in poor visibility caused by excess dust. The car went into a gutter and crashed into a tree, and Renault sustained a horrific wound in the side of his head and dislocated his shoulder. Fellow competitor Leon Théry stopped his Decauville in order to help Renault and his riding-mechanic Vauthier, still trapped in their car. No doctors were on hand, but Théry found one at the next village and sent him to the place of accident- the doctor rode a bicycle to get to the accident. The doctor conveyed Renault back to the nearest hospital in Grand Poitiers, where Renault succumbed to his injuries two days later, while Vauthier survived with minor injuries. Accidents continued throughout the day; cars hit trees and disintegrated, they overturned and caught fire, axles broke and inexperienced drivers crashed on the rough roads. The race was eventually called off by the French government and there was no declared winner. The cars were impounded by the French authorities, towed to the nearest rail stations by horses and transported back to Paris by train. The race created a political uproar in France, and a French magazine did their own investigation into the race. Speed, dust created by the cars, poor organization and lack of crowd control were to blame for these tragedies and even French Prime Minister Émile Combes was held partially responsible because he was the ultimate authority on allowing the race to proceed.

Other races were organized by American newspaper publisher James Gordon Bennett called the Gordon Bennett Cup, 4 of which were in France. 3 city-to-city races in 1900, 1901 and 1902, all starting in Paris were organized by Bennett and they attracted top racers from the United States and Western Europe. But after the 1903 Paris-Madrid race, the French government banned point-to-point car races on open public roads, so Bennett moved the 1903 race to Ireland on a closed circuit 2 months after Paris-Madrid, the first of its kind. This race was won by Belgian Camille Jenatzy in a Mercedes, who was one of the bravest and most fearless racing drivers of his time. The 1904 race was held in western Germany while the last Gordon Bennett Cup race was held in an 137 km (85 mi) circuit in Auvergne in south-central France. The race started in Clermont-Ferrand, and was run over 4 laps, and was won by Théry in a Brasier.

The French Grand Prix, open to international competition was first run on 26 June 1906 under the auspices of the Automobile Club de France in Sarthe with a starting field of 32 automobiles. The Grand Prix name ("Great Prize") referred to the prize of 45,000 French francs to the race winner. The franc was pegged to gold at 0.290 grams per franc, which meant that the prize was worth 13 kg of gold, or US$210,700 adjusted for inflation. The earliest French Grands Prix were held on circuits consisting of public roads near towns through northern and central France, and they usually were held at different towns each year, such as Le Mans, Dieppe, Amiens, Lyon, Strasbourg, and Tours. Dieppe in particular was an extremely dangerous circuit – 9 people (5 drivers, 2 riding mechanics, and 2 spectators) in total were killed at the three French Grands Prix held at the 79 km (49-mile) circuit.

The 1906 race was the first ever national race named "Grand Prix" (the "Grand Prix" mention appeared in France in 1900 as a sub-category name for entries for the Circuit du Sud-Ouest in Pau, where the word "Grand Prix" was initially used for horse racing competitions, the name Grand Prix was then used to describe the whole race in 1901); other, later, international events in the 1900s and 1910s in Europe and the United States had their own names with the term "Prize" in them, such as Grand Prize in America or Kaiserpreis (English: Emperor's Prize) in Germany. The French Grand Prix race was run on a very fast 66-mile (106 km) one-off anti-clockwise closed public road circuit east of the small western French city of Le Mans, starting in the village of Saint-Mars-la-Briere. It then went down the Route D323 and turned a hard left onto Route D357 near the commune of Yvre-l-Eveque onto a 4-mile straight towards the village of La Butte, then down a 15-mile straight through Bouloire and then into a twisty section in Saint-Calais. The circuit then went north on Route D1 through Berfay and then entered a purpose-built twisty section made of wooden logging track in a forest before Vibraye and then went north again, entering a series of fast corners in and near Lamnay, and then turned west at La Ferte-Bernard. The circuit then went down Route D323 again and down multiple straights 3 to 6 miles long with a few fast corners at Sceaux-sur-Huisne and Conerre, before returning to the pits at Saint-Mars-la-Briere. Circuits in Europe that went through multiple rural towns like this one became ever more common on public road circuits in France and other European countries. Long straights also became a staple of circuits in France, particularly at future iterations of the relocated Sarthe circuit at Le Mans- a city that would host another race that would become a fixed staple in motor racing circles. The Hungarian Ferenc Szisz won this very long 12‑hour race on a Renault from Italian Felice Nazzaro in a Fiat, where laps on this circuit took just under an hour and the horse carriage road surface was made of dirt; even so this did not stop the fastest lap average speed being 73.37 mph (118.09 km/h)- an astonishingly fast speed for the time. The 1908 race saw Mercedes humiliating the French organizers and finishing 1-2-3 at the lethal circuit at Dieppe, where no less than 4 people were killed during the weekend. The 1913 race was won by Georges Boillot on a one-off 19-mile (31 km) circuit near Amiens in northern France. Amiens was another deadly circuit – it had a 7.1 mile straight and 5 people were killed during its use during pre-race testing and the race weekend itself.
