The 2020–21 NWHL season was the sixth season of the National Women's Hockey League in North America. Due to the ongoing COVID-19 pandemic, the season was held in a bubble in Lake Placid, New York, from January to February 2021, with all five teams returning from the previous season, along with the Toronto Six expansion team as the first Canada-based team to play in the league. The season was suspended again due to positive cases of COVID-19 within the bubble. On March 8, 2021, the league announced that the Isobel Cup playoffs would re-commence on March 26 and 27 at Warrior Ice Arena in Brighton, Massachusetts.
