The 1925–26 National Hurling League was the first edition of the National Hurling League, which ran from 27 September 1925 until 16 May 1926.
The seven participating teams in Division 1 were Cork, Dublin, Galway, Kilkenny, Laois, Limerick and Tipperary who agreed to play a six game format whereby each team would play each of their six rivals once with two points awarded for a win and one point awarded for a drawn game.
The two teams with most points at the completion of the season would play a final, with the winners being declared National Hurling League champions.

Division 2 was contested by five teams: Clare, Kerry, Offaly, Waterford and Wexford.
