2010–11 Division 1 season (Swedish ice hockey)

2010–11 was the 12th season that Division 1 functioned as the third-level of ice hockey in Sweden, below the second-level HockeyAllsvenskan and the top-level Elitserien (now the SHL).

Format
The 57 participating teams played the first half of the season in six groups divided geographically. The successful teams then moved into three new groups (the Allettan groups), while the remaining teams played in a continuation of their smaller existing groups. The teams with the worst records in these continuation groups were then forced to defend their places in Division 1 against challengers from Division 2 (see "relegation tournament" below) in a round-robin tournament called Kvalserien till Division 1. Meanwhile, the successful teams from the Allettan groups along with the group winners of the continuation groups played a playoff to determine who would have a chance to compete for promotion to the second-tier league HockeyAllsvenskan in Kvalserien till HockeyAllsvenskan.
