The 2021 Clare Senior Hurling Championship was a competition in hurling that was the 126th 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.[3]
The 2021 Championship changed 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.
