The 2020 Antrim Senior Hurling Championship was the 120th staging of the Antrim Senior Hurling Championship since its establishment by the Antrim County Board in 1901. The championship was postponed indefinitely due to the impact of the COVID-19 pandemic on Gaelic games, before eventually beginning on 9 August 2020 and ending on 13 September 2020.
