The 2020–21 Naisten Liiga season was the thirty-eighth season of the Naisten Liiga, Finland's elite women's ice hockey league, since the league’s creation in 1982. The season began, as scheduled, on 5 September 2020, making the Naisten Liiga the first women's national ice hockey league in Europe and, quite likely, in the world to return to play for the 2020–21 season.
