The 2023–24 HockeyAllsvenskan season is the 19th season of HockeyAllsvenskan, the second-highest professional ice hockey league in Sweden. The season consists of 14 teams playing a regular season in which each team played each other team four times—twice at home and twice away. The regular season is followed by a series of promotion and relegation tournaments, with the teams finishing first through tenth participating in promotion playoffs, and those finishing thirteenth and fourteenth forced to requalify to avoid relegation to Hockeyettan. ^[1]

For the 2023–24 season, there were three team movements. Modo Hockey was promoted to the SHL as reigning 2023 HockeyAllsvenskan champions. Despite losing the play-out, Västerviks IK remained in the league as HC Vita Hästen was forced out due to a club bankruptcy. ^[2] Nybro Vikings and Kalmar HC were moved up from Hockeyettan.
