Guldbagge Award for Best Actor in a Leading Role

The Guldbagge for Best Actor in a Leading Role is a Swedish film award presented annually by the Swedish Film Institute (SFI) as part of the Guldbagge Awards (Swedish: "Guldbaggen") to actors working in the Swedish motion picture industry.

Winners and nominees
Each Guldbagge Awards ceremony is listed chronologically below along with the winner of the Guldbagge Award for Actor in a Leading Role and the film associated with the award. Before 1991 the awards did not announce nominees, only winners. In the columns under the winner of each award are the other nominees for best actor, which are listed from 1991 and forward.

For the first nineteen ceremonies, the eligibility period spanned two calendar years. For example, the 2nd Guldbagge Awards presented on 15 October 1965, recognized films that were released between July 1964 and June 1965. Starting with the 20th Guldbagge Awards, held in 1985, the period of eligibility became the full previous calendar year from 1 January to 31 December. The Awards presented at that ceremony were in respect of 18 months of film production owing to the changeover from the broken calendar year to the standard calendar year during 1984. Due to a mediocre film year, no awards ceremony was held in 1971.
