The 2020–21 OHL season would have been the 41st season of the Ontario Hockey League. After the 2019–20 OHL season was curtailed due to the COVID-19 pandemic, the league initially planned to play a full 68-game regular season beginning in September 2020. However, due to continued public health orders and increasing cases of COVID-19 in Ontario, the league eventually shortened the planned season and postponed it indefinitely in December 2020. By April 2021, the league ultimately cancelled the season.
