The 2021–22 HockeyAllsvenskan season was the 17th season that the second tier of Swedish ice hockey operated under that name. The series consists of 14 teams playing a regular season in which each team play each other team four times, twice at home and twice away. This is followed by a series of promotion and relegation tournaments, with the teams finishing first through tenth participating in promotion playoffs, and the teams finishing 13th and 14th forced to requalify to avoid relegation to the Hockeyettan.[2]
The following shows the top ten players who led the league in points, at the conclusion of matches played on 16 March 2022.[3] If two or more skaters are tied (i.e. same number of points, goals and played games), all of the tied skaters are shown.
