Jonathan "Jon" Ekerold (born 8 October 1946) is a South African former Grand Prix motorcycle road racer.
Born in Johannesburg, South Africa, Ekerold is one of the few racers in the modern era to have won a world championship as a privateer without the benefit of a motorcycle manufacturer's support when he defeated Kawasaki factory racing team rider Anton Mang for the 1980 350cc Grand Prix road racing world championship. Ekerold rode a self-modified Yamaha TZ350 engine in a Bimota chassis during his championship season. He also won the Ulster Grand Prix once and finished second at the Isle of Man TT twice.
