The 1977 Individual Speedway World Championship was the 32nd edition of the official World Championship to determine the world champion rider.
History was made in the 1977 final when Ivan Mauger of New Zealand equalled Ove Fundin's title record of five World Championship wins. Mauger had gone close to equalling the record before and finally achieved it in Sweden, the home of Fundin. In a decisive 18th heat Mauger won from his nearest challenger Ole Olsen in the re-run, after Olsen was forced to lay his bike down to avoid hitting John Boulger in the original start. Olsen was leading Mauger at the time. In re-run Olsen just got one point riding on his spare bike. Defending champion Peter Collins won his last ride to claim the silver medal despite riding with a broken left leg, but Olsen won the bronze medal run-off against young English rider Michael Lee.
