The 2019–20 Naisten Liiga season was the thirty-seventh season of the Naisten Liiga, the premier level of women's ice hockey in Finland, since the league’s establishment in 1982. The postseason was cancelled by the Finnish Ice Hockey Association on 12 March 2020 in response to public health concerns surrounding the COVID-19 pandemic. The 2020 Aurora Borealis Cup Final between Kiekko-Espoo and KalPa was scheduled to begin on 14 March 2020. With the cancellation of the remainder of the season, the 2019–20 season became the first and only Naisten Liiga season to date in which the Finnish Championship was not awarded.
