The 2021 FFA Cup was the eighth season of the FFA Cup, the main national soccer knockout cup competition in Australia. Thirty-two teams contested the competition proper from the round of 32, including 10 of the 12 A-League teams (with two teams not qualifying), 21 Football Australia (FA) member federation teams determined through individual state qualifying rounds, as well as the 2019 National Premier Leagues champions (Wollongong Wolves from New South Wales). The competition format and timing was impacted by the on-going COVID-19 pandemic in Australia.
