The 1923 24 Hours of Le Mans, officially the 24 Hours Grand Prix of Endurance (French: Grand Prix d'Endurance de 24 Heures), was the inaugural Grand Prix of Endurance, and took place on 26 and 27 May 1923. The race was also an excellent exhibition of machine endurance and reliability. Thirty cars finished the event, a number not equalled at Le Mans again until 1993.
