The 2012–13 National League 2 North was the third season (twenty-sixth overall) of the fourth tier (north) of the English domestic rugby union competitions since the professionalised format of the second division was introduced. The league system was 4 points for a win, 2 points for a draw and additional bonus points being awarded for scoring 4 or more tries and/or losing within 7 points of the victorious team. In terms of promotion the league champions would go straight up into National League 1 while the runners up would have a one-game playoff against the runners up from National League 2 South (at the home ground of the club with the superior league record) for the final promotion place.
