The 1906 Grand Prix de l'Automobile Club de France, commonly known as the 1906 French Grand Prix, was a motor race held on 26 and 27 June 1906, on closed public roads outside the city of Le Mans. The Grand Prix was organised by the Automobile Club de France (ACF) at the prompting of the French automobile industry as an alternative to the Gordon Bennett races, which limited each competing country's number of entries regardless of the size of its industry. France had the largest automobile industry in Europe at the time, and in an attempt to better reflect this the Grand Prix had no limit to the number of entries by any particular country. The ACF chose a 103.18-kilometre (64.11 mi) circuit, composed primarily of dust roads sealed with tar, which would be lapped six times on both days by each competitor, a combined race distance of 1,238.16 kilometres (769.36 mi). Lasting for more than 12 hours overall, the race was won by Ferenc Szisz driving for the Renault team. FIAT driver Felice Nazzaro finished second, and Albert Clément was third in a Clément-Bayard.
