1980–81 Division 1 season (Swedish ice hockey)

1980-81 was the sixth season that Division 1 operated as the second tier of ice hockey in Sweden, below the top-flight Elitserien (now the SHL).

Division 1 was divided into four starting groups, based on geography. The top four teams in the group would continue to the playoffs to determine which clubs would participate in the qualifier for promotion to Elitserien. The bottom team in each group was relegated directly to Division 2 for the 1981–82 season. The second-to-last place team in each group played in a relegation series to determine their participation in the next season.
