1991 Individual Speedway World Championship

The 1991 Individual Speedway World Championship was the 46th edition of the official World Championship to determine the world champion rider.

Diminutive Danish rider Jan O. Pedersen won his first and only World Championship with a 15-point maximum from his five rides, the last time a rider would have a perfect score in the Final. Local favourite Tony Rickardsson finished second with 12 points, with triple champion Hans Nielsen of Denmark finishing third on 11 points after defeating fellow Dane Tommy Knudsen in a run-off. Defending champion Per Jonsson finished in ninth place with 7 points.
