The 1962 South African Grand Prix, formally titled the 9th International RAC Grand Prix of South Africa, was a Formula One motor race held at East London on 29 December 1962. It was the ninth and final race in both the 1962 World Championship of Drivers and the 1962 International Cup for Formula One Manufacturers. The 82-lap race was won by Graham Hill driving a BRM, the Englishman taking his first Drivers' Championship in the process, with New Zealander Bruce McLaren and local driver Tony Maggs second and third respectively in works Cooper-Climaxes.
Hill went into the race with a nine-point lead in the Drivers' Championship over Scotland's Jim Clark, driving a works Lotus-Climax. A Clark win would give him the Championship, regardless of Hill's performance, because only the top 5 results counted for the Championship. After taking pole position, Clark led comfortably until an oil leak 20 laps from the finish forced him to retire, handing the Championship to Hill. The win also gave BRM their first, and only, Manufacturers' Cup.
