1978 Individual Speedway World Championship
The 1978 Individual Speedway World Championship was the 33rd edition of the official World Championship to determine the world champion rider.
Ole Olsen won his third world crown. The final was sponsored by the Sunday Mirror and was attended by 86,500. Gordon Kennett took silver on the day of his 25th birthday and American Scott Autrey won the bronze medal run-off defeating Dave Jessup and Jerzy Rembas. Dave Jessup was effectively denied a World title when after leading in heat 3 he suffered a bike malfunction and finished last in the heat. He then scored 11 points from his remaining rides which would have been enough to take the crown if he had won heat 3.
