2020 National Hurling League

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.
Eir Sport and RTÉ provide live TV coverage of the league on Saturday nights. TG4 broadcast Sunday afternoon games. The highlights programmes are RTÉ2's League Sunday on Sunday evenings, TG4's "GAA 2020" on Monday evenings and Eir Sport's Allianz Leagues Reloaded on Wednesday evenings.
Limerick were the winners, defeating Clare in the final on 25 October.

League structure
Thirty-five teams compete in the 2020 NHL –
All thirty-two county teams from Ireland take part. London, Lancashire and Warwickshire complete the lineup.
Each team plays all the other teams in their division once, either home or away. Two points are awarded for a win, and one for a draw.
The Division 1 semi-finals had been proposed to finish on the day the games are played avoiding the need for replays. If a semi-final is level after the initial seventy minutes, still level after two ten minute periods of extra time played each way, and still level after two further five minute periods of extra time, the outcome is to be decided by a free-taking competition. This is intended to prevent games from going to a replay and allow the league finals to be held on the scheduled date.
