The 2021 Kerry Senior Football Championship was the 120th edition of Kerry GAA's premier Gaelic football tournament for senior teams in County Kerry, Ireland. The tournament consists of 16 teams (8 club teams and 8 divisional teams), with the winners representing Kerry in the Munster Senior Club Football Championship if they are a club team. If the winners are a divisional team the winners of the Kerry Club Football Championship represent the county.
The championship usually has a back-door format for the first two rounds before proceeding to a knock-out format. Generally, any team to lose two matches will be knocked out of the championship. This year however, due to the COVID-19 pandemic seen the competition employ a straight knockout format.
