2021 Clare Senior Hurling Championship
The 2021 Clare Senior Hurling Championship is a competition in hurling that will be the 123rd staging of the Clare Senior Hurling Championship since its establishment by the Clare County Board in 1887. With Sixmilebridge having won back-to-back titles in 2019 and 2020, they are looking to be the first Clare club team to win a three-in-a-row since Newmarket-on-Fergus in 1973. They defeated near-neighbours O'Callaghan's Mills in the 2020 final who were contesting their first final since 1993 which they ironically also lost to Sixmilebridge. The  2021 Championship will this year stray from the regular layout in adopting a group stage format. 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 normal sixteen-team championship format.
