2020–21 I-League

The 2020–21 I-League (known as the Hero I-League for sponsorship reasons) was the 14th season of the I-League, one of the top tier Indian professional football leagues, since its establishment in 2007. The tournament was hosted in bio-secure bubble across four venues in Kolkata due to the COVID-19 pandemic situation in India.

Mohun Bagan was declared the champion of the 2019–20 season after the cancellation of matches due to the COVID-19 pandemic, since the second placed team could not catch up even if all 20 games were completed. However, following Mohun Bagan's merger with Indian Super League (ISL) club ATK, the club began competing in the ISL from the 2020–21 ISL season.

Throughout the First Phase, Churchill Brothers kept its dominance with an unbeaten run of 11 games, while in the Second Phase, Gokulam Kerala, Churchill Brothers and TRAU traded the lead several times throughout the Championship Stage. Entering the final matchday, Gokulam Kerala were ahead on goal difference. However, with the Gokulam and TRAU facing off, either team could claim the title with a win. A draw in the Gokulam Kerala–TRAU match and a win were needed for Churchill Brothers to be crowned champions. The game ended in a 4–1 win for Gokulam, giving the Malabarians their first I-league title and qualification for the AFC Cup. NEROCA finished bottom of the Relegation Stage and were to relegated, but were reinstated by AIFF after the viewing the situation of the COVID-19 pandemic.

Changes in rules and regulations

 * Due to the COVID-19 pandemic, this season's league format was shortened. All teams will face each other once in the first leg of the league, then they will be divided into two different groups. According to points table from first leg, top six teams will face each other once again in the Championship stage, where the team with most points (cumulative points collected from all fifteen matches) will be declared the winner of the league and qualify for the 2022 AFC Cup group stage. The other five teams will play against each other in a Relegation stage where the team with the lowest points (cumulative points collected from all fourteen matches) will be relegated to the 2nd Division League.
