National League 2 North, (which before September 2009 was known as National Division Three North) is a level four league in the English rugby union system and provides mostly amateur competition for teams in the northern half of England. From 2009–10 the RFU restructured the league system in England, and this league was expanded from fourteen to sixteen teams. Participating clubs are from the English Midlands and Northern England. Each team plays thirty league games on a home and away basis. The champion club is promoted to National League 1 and the runner-up participates in a one-off play-off with the runner-up of National League 2 South for promotion. Relegation is to either the National League 3 Midlands or National League 3 North leagues depending on where the teams are based.
