The 2021 Clare Senior Football Championship was the 126th staging of the Clare Senior Football Championship since its establishment by the Clare County Board in 1887.
The 2020 champions, and holders of the Jack Daly Cup are Kilmurry-Ibrickane who won their sixteenth overall title after defeating Cratloe in a repeat of the 2016 final, also won by Kilmurry-Ibrickane.
In 2020 a decision was made to not relegate any team from any championship in Clare due to the Coronavirus Pandemic. As a result, there will be two teams relegated from senior level down to intermediate for 2022 in order to revert to the preferred twelve-team championship format.
