2020–21 NL season

The 2020–21 National League season is the 83rd season of Swiss professional ice hockey and the fourth season as the National League (NL).

ZSC Lions are the defending regular season winners. Due to the 2020 coronavirus outbreak in Switzerland there is no defending champion as the previous season's playoffs were cancelled.

Due to the 2019–20 league qualification series also being cancelled, the participating teams remained the same as the previous season.

The league announced changes to the format ahead of the season, meaning that 52 games rather than 50 would be played in the regular season. The playoffs would also be re-formatted, so that the top 6 teams now qualified directly for the quarter-finals, with the next four teams playing in pre-playoffs for the remaining two spots. There would also be no relegation from the season. The two pre-playoffs series were played in a best-of-three, the quarter finals in a best-of-seven and the semi-finals and final in a best-of-five. The series were shortened to allow enough time for the national team to prepare for the 2021 IIHF World Championship.

EV Zug won the regular season with 6 games remaining, having already clinched their club record points total, surpassing their previous best of 98 points from the 2011–12 season. With two games remaining EV Zug broke the record for most points in a single regular season, held by HC Davos from the 2010–11 season. Whilst this season was the first to be 52 games in length, EV Zug passed the milestone in the same number of games as the previous record holders.

EV Zug swept Genève-Servette HC 3-0 in the final to win its first NL title since 1998.

Regular season
Due to coronavirus cases in both EHC Biel and SC Bern forcing late season stoppages to training, not all regular season games could be completed, and the league would use points per game to determine the final regular season standings.
