The 1984 Individual Speedway World Championship was the 39th edition of the official World Championship to determine the world champion rider. Without former champions Ivan Mauger, Ole Olsen, Peter Collins, Michael Lee, and Bruce Penhall, the 1984 World Final, held for the eighth time at the Ullevi Stadium in Göteborg, Sweden, was seen by some as the battle of the second tier riders. Though history would ultimately prove the first and second placed riders as among the best Motorcycle speedway has ever seen, winning every World Final between them until the end of the 1980s. Dane Erik Gundersen won his first Speedway World Championship from countryman Hans Nielsen who defeated American Lance King in a run-off for second and third places. Defending champion Egon Müller of West Germany could not reproduce his 1983 World Final form and finished 14th with just 3 points from his 5 rides. 1983 runner-up Billy Sanders of Australia, the track record holder at Ullevi, fared marginally better, finishing 11th with just 5 points.
