The competition is played between Leinster Lightning, Northern Knights and North-West Warriors.
The North-West Warriors won the 2014 competition, winning by three points from Leinster Lightning.
The final days matches, scheduled for Pembroke CC in Dublin, were abandoned due to bad weather, meaning that the Warriors maintained their lead at the top of the table.
The player of the tournament was David Rankin of the North-West Warriors.
The Inter-Provincial Series has been funded at least partly by the ICC via their TAPP programme.
