The 2020 National Hurling League was the 89th season of the National Hurling League for county teams. Division 1 was restructured in 2020 into two groups of approximately equal strength. The league was originally scheduled to end on 29 March 2020. The public health measures introduced to combat the COVID-19 pandemic in Ireland resulted in most of the final stages being delayed to October and the Division 1 final stage being reduced from five games to one. Limerick were the winners, defeating Clare in the final on 25 October.
