The 2020–21 season was the 124th season of competitive football by Heart of Midlothian (Hearts), with the team participating in the Scottish Championship. It was the club's first season of play in the second tier of Scottish football since 2015, and only the second since 1983, having been relegated from the Scottish Premiership, after the previous season was ended early due to the COVID-19 pandemic in Scotland. On 10 April 2021, Hearts earned automatic promotion back to the Scottish Premiership, having been in first place for most of the season. They also competed in this season's Scottish League Cup and Scottish Cup, losing in the second round of each competition respectively.
