The 2021 Indy Eleven season was the club's eighth season of existence, their eighth consecutive season in the second tier of American soccer, and their fourth season in the league now named the USL Championship. This article covers the period from November 2, 2020 (the day after the ultimately cancelled 2020 USLC playoffs final) to the end of the 2021 USLC season (tentatively scheduled for November 2021).

See main article: 2021 U.S. Open Cup. On March 29, 2021, the U.S. Soccer Federation announced a truncated format for the 2021 U.S. Open Cup, with 16 clubs participating, entering at the same time in a Round of 16. The format included just four teams from the USL Championship, the four semi-finalists from the 2020 playoffs (El Paso, Louisville, Phoenix, and Tampa). Due to the fact that Indy failed to qualify for the 2020 USLC playoffs, the club was eliminated from the 2021 U.S. Open Cup.[1]
