The Auroraliiga is the national premier league for women's ice hockey in Finland. Founded by the Finnish Ice Hockey Association as the Naisten SM-sarja (NSMs; lit. 'Women's Finnish Championship series') in 1982, it was known as the Naisten Liiga (NSML;lit. 'Women's League') from 2017 until being rebranded as Auroraliiga in 2024. The league comprises approximately 225 players across nine teams.
Kiekko-Espoo has been the dominating force of the Auroraliiga in the 21st century, winning sixteen Finnish Championships from 1999 to 2022. Tampereen Ilves is the second most successful club in league history, with ten championship titles. Ilves are the only organization to have iced a team in every season since the league's inception.
A majority of teams in Auroraliiga share their names with men's professional teams in the Liiga or Mestis – HIFK, HPK, Ilves, KalPa, Kiekko-Espoo, Kärpät, Lukko, RoKi, TPS – but the women's teams have historically received few resources and limited promotion from the affiliated men's clubs. In recent years progress has been made in building better relationships between the men's and women's teams; most men's clubs now provide some support to their women's counterparts by advertising games together or helping secure sponsorships.
