The 2021 National Hurling League was the 90th season of the National Hurling League for county teams. The English county teams (London, Warwickshire and Lancashire) did not compete due to the COVID-19 pandemic travel restrictions. In February 2021 it was announced that the league would be delayed due to the impact of the COVID-19 pandemic on Gaelic games and that cancelling it would be a last resort. The league began on 8 May 2021. Galway and Kilkenny were the joint winners.
