The 1970 South African Grand Prix, formally titled the Fourth South African Grand Prix (Afrikaans: Vierde Suid-Afrikaanse Grand Prix), was a Formula One motor race held at Kyalami Circuit on 7 March 1970. It was the first round of the 1970 Formula One season. It was also the last Formula One victory for triple world champion Jack Brabham.
Two times World Champion and five times Monaco Grand Prix winner Graham Hill, driving a Lotus 49C for Rob Walker, made his return to racing after a life-threatening crash in the 1969 United States Grand Prix. Despite extensive knee surgery that left Hill with minimal mobility, he finished sixth. Hill rated this achievement as among his finest. After the race, he could not get out of the car by himself and had to be lifted out.
