The 2015–16 National League 2 North is the seventh season (29th overall) of the fourth tier of the English domestic rugby union competitions since the professionalised format of the second division was introduced.

There was talk of this being the last season in this format due to RFU changes to tier four which were supposed to result in a restructuring of the league from two regional divisions (north and south) to three (north, south-east and south-west) for the 2016–17 season but this seems to have been put on hold due to protests from the northern clubs who stood to lose revenue from a smaller fixture list.

In the end it was Sandal who went down after one season spent in National League 2 North, losing their final game against Luctonians, while their relegation rivals all won.

It was a particularly interesting contest between Sandal and fellow promoted club, Sale, who were actually in the final relegation spot on the last day (although they did have a rescheduled game still to play) but the Heywood Road side won against high flying Caldy to stay in the division.

In the end Old Albanian were too good for Sedgley Park, winning 24 – 0 to claim the final promotion place to the 2016–17 National League 1.
