The 1991 Australian Individual Speedway Championship was the 1991 version of the Australian Individual Speedway Championship organised by Motorcycling Australia. The final took place on 27 January at the Arunga Park Speedway in Alice Springs in the Northern Territory.
Sydney's Craig Boyce won his first Australian championship, defeating defending champion Glenn Doyle, with veteran Glyn Taylor finishing third (both from Perth). Boyce was unbeaten on the night, securing his first Australian Championship.
It was the only time the Australian Solo Championship final has been held in the Northern Territory.

After a number of high-profile riders had failed to qualify for the Australian final, a special qualifying round was held at Arunga Park the week before the finals. Unfortunately the round was not well attended after it was revealed that only the top five riders would be paid travel money prompting some of those higher profile riders to boycott the event, most notably NSW rider Stephen Davies who had placed 2nd and 3rd in the previous two Australian titles.
