The 1981 Individual Speedway World Championship was the 36th edition of the official Motorcycle speedway World Championship to determine the world champion rider.^{[1][2][3][4][5]}

It was also the last of a record 26 times that London's world famous Wembley Stadium hosted the World Final. It also marked the final time that the stadium would be used for any speedway. In future years when the final was held in England, it would be held at the Odsal Stadium in Bradford until the advent of the Speedway Grand Prix series in 1995. The 1981 Final was held before a reported crowd of 92,500, just shy of the Wembley record of 95,000 set at the 1938 World Final.

Bruce Penhall became the first American to win the World Championship since Jack Milne in 1937. As a past World Championship winner at Wembley, the 74-year-old Milne was a special guest at the event and saw Penhall end America's 44 year Individual World Championship drought. Though he remained undefeated until his last ride when he only needed to finish 3rd to win the Championship (he finished that race in second behind his rival Kenny Carter), Penhall was forced to work hard for his maiden World Championship. In both Heat 7 and Heat 14 he was second for over 3½ laps behind Ole Olsen and Tommy Knudsen respectively before passing both in the run to the line. Olsen would defeat Knudsen in a runoff for second and third places after both finished on 12 points. The triple World Champion gaining some revenge on his younger countryman after Knudsen had defeated Olsen in the first heat of the meeting.

In Heat 6, Erik Gundersen set a new four lap record of 66.8 seconds for the track and as this was the final speedway meeting at Wembley it will forever be the track record.
