The Nine Hours of Kyalami was an endurance sports car race contested in South Africa from the late 1950s until the late 1980s. The first races were held at a circuit at the Grand Central Airport near Midrand. In 1961, the event moved to the newly constructed Kyalami Circuit.
From 1965 to 1973, the race was the centerpiece of the South African Springbok Trophy Series. In 1974, the event was part of the World Sportscar Championship, switching to a 6 hour/1000 kilometre format. From 1975 until 1979, the race was held for touring cars. The race returned to sports cars and its 9 hour duration in 1981 and 1982, before being shortened to 1000 km and becoming part of the World Sportscar Championship once more in 1983 and 1984. After not being held in 1985 due to circuit construction, a 500 km event was contested from 1986-1988. It was revived as a 2 hour, 30 minute, race as part of the SportsRacing World Cup from 1998-2000.
