The 1980 24 Hours of Le Mans was the 48th Grand Prix of Endurance, and took place on 14 and 15 June 1980. It was the seventh round of both the World Championship for Makes and World Challenge for Endurance Drivers. With neither the Porsche nor Renault works teams contesting the big Group 6 sports-cars for outright victory, it left the prospects open for a privateer victory from Joest, Rondeau or De Cadenet, or from Group 5 again, if they were to fail. The wet weather throughout the race further added to the uncertainty, reducing the advantage of the more powerful cars.

The 24 Hours of Le Mans is an endurance-focused sports car race held annually near the town of Le Mans, France. It is widely considered to be one of the world's most prestigious races, and is one of the races—along with the Monaco Grand Prix and Indianapolis 500—that form the Triple Crown of Motorsport, and is also one of the races alongside the 24 Hours of Daytona and 12 Hours of Sebring that make up the informal Triple Crown of endurance racing. Run since 1923, it is the oldest active endurance racing event in the world.
