1990 Individual Speedway World Championship

The 1990 Individual Speedway World Championship was the 45th edition of the official World Championship to determine the world champion rider.

The final was held at the Odsal Stadium in Bradford, England. It would be the 28th and last time the world final would be held in England under the traditional single meeting format.

Sweden's Per Jonsson won his only World Individual Championship to become the first Swedish World Champion since Anders Michanek in 1974 and became the first rider to win both the Under-21 and Senior World Championships having previously won the 1985 Under-21 World Championship. Jonsson defeated Shawn Moran from the United States in a run-off after both finished the meeting on 13 points. Moran was later stripped of his second place by the FIM for failing a drug test taken at the Overseas Final. After Moran's disqualification, the FIM did not upgrade the placings, thus records show no second place rider for the 1990 World Final. Australian youngster Todd Wiltshire, believed by many judges to be one who would be making up the numbers in his first World Final, finished third with 12 points after winning his first two rides.

After having won each World Final since 1984, including five 1-2 finishes and taking all podium places in 1988, the 1990 World Final saw no Danish riders finishing on the podium for the first time since 1983. Defending champion Hans Nielsen, the only Dane in the field following an injury to Jan O. Pedersen which kept him from riding, finished in 4th place with 11 points.

Notes:
 * a. Shawn Moran scored 13 points and lost the run-off to Per Jonsson. However, Moran had failed a random drug and alcohol test taken three months earlier at the Overseas Final, and was subsequently disqualified from second place. The FIM did not upgrade the standings and the official records show no second place rider.
