The 2015 National Hurling League was the 84th staging of the National Hurling League. Waterford won their first title since 2007 after a 1-24 to 0-17 win against Cork in the final on 3 May.

TG4 and Setanta provided live coverage of the league with highlights shown on RTÉ2 on Sunday nights.

34 teams play in the 2015 NHL. There are six teams in the top five divisions, and four teams in Division 3B. Each team plays each other once, either home or away. 2 points are awarded for a win, and 1 for a draw. Where two teams are level on points, the team that won the head-to-head match is ranked ahead. If this game was a draw, points difference (total scored minus total conceded in all games) is used to rank the teams. Where three or more teams are level on points, points difference is used to rank them.
