The 2021 Limerick Senior Hurling Championship was the 127th staging of the Limerick Senior Hurling Championship since its establishment by the Limerick County Board in 1887. The draw for the group stage placings took place on 30 June 2021. The championship began on 3 September 2021 and ended on 24 October 2021.
Na Piarsaigh were the defending champions, however, they were beaten by Patrickswell in the semi-final.[1][2] Monaleen were relegated from the championship after being beaten in a playoff by Blackrock.[3]
