2021–22 Liiga season

The 2021–22 SM-liiga season was the 47th season of the SM-liiga, the top level of ice hockey in Finland, since the league's formation in 1975.

Standings
Top six advanced straight to the quarter-finals, while teams between 7th and 10th positions played a wild card round for the final two spots. The Liiga is a closed series and thus there is no relegation. The top 3 teams of the regular season qualified for the Champions Hockey League and the 4th team to the Spengler Cup.

The match program was on hiatus during the EHT, Karjala Cup from 7 to 14 November. In December, Christmas was a week-long match break. In December, a new ice rink named Tampere Deck Arena (Nokia Arena) was opened in Tampere for the use of Ilves and Tappara. Two matches were played in the new arena on 19 February, when Ilves hosts his own in the afternoon and Tappara in the evening.
