The 2019–20 Liiga season is the 45th season of the Liiga (formerly SM-liiga), the top level of ice hockey in Finland, since the league's formation in 1975. The last two game days (12 and 14 March 2020) of the regular season were scheduled to be played in front of an empty arena due to the Finnish government advising that all public events with more than 500 attendees will be cancelled or postponed. On 13 March, the rest of the season, which included the final round of the regular season and all of playoffs, was cancelled due to the COVID-19 pandemic.
