1986–87 Division 1 season (Swedish ice hockey)

1986-87 was the 12th season that Division 1 operated as the second tier of ice hockey in Sweden, below the top-flight Elitserien (now the SHL).

Format
Division 1 was divided into four starting groups of 10 teams each. The top two teams in each group qualified for the Allsvenskan, while the remaining eight teams had to compete in a qualifying round. The teams were given zero to seven bonus points based on their finish in the first round. The top team from each qualifying round qualified for the playoffs. The last-place team in each of the qualifying groups had to play in a relegation series in an attempt to avoid relegation to Division 2.

Of the eight teams in the Allsvenskan, the top team qualified directly for promotion to the Elitserien, while the second place team qualified for the Kvalserien, which offered another opportunity to be promoted. The third to sixth place teams in the Allsvenskan qualified for the playoffs. The two playoff winners qualified for the Kvalserien, in which the first-place team qualified for the following Elitserien season.
