2020–21 EFL Trophy

The 2020–21 EFL Trophy, known as the Leasing.com Trophy before 28 October 2020 and later the Papa John's Trophy for sponsorship reasons, was the 40th season in the history of the competition, a knock-out tournament for English football clubs in League One and League Two of the English football system, and also including 16 Premier League and Championship "Academy teams" with Category One status.

Salford City were the defending champions; however, the 2020 final was delayed due to the COVID-19 pandemic until the day prior to the 2021 final. Hence, for most of the tournament, Portsmouth (who won the 2019 final and were also in the 2020 final) were the most recent champions.

Sunderland won the trophy for the first time after beating Tranmere Rovers 1–0 in the final.

• 48 clubs from League One and League Two.
• 16 invited Category One Academy teams.
• Expelled clubs were automatically eliminated from the tournament.
• Category One teams relegated to League One missed out on having academies participate in the following tournament.

Four Premier League clubs with Category One academies did not participate: Burnley and Crystal Palace, both in their first full season of Category One status, and Everton and Tottenham Hotspur, who both played in the previous year's competition but declined to participate in this one. A fifth Premier League club's academy, Sheffield United, did not have Category One status. As a result, the academy of Championship-side Norwich City was invited instead.
