The 2013 Interprovincial Championship was the first season of the Inter-Provincial Championship, the domestic multi-day cricket competition of Ireland. The competition comprised three contestants: Leinster Lightning, Northern Knights and North West Warriors.
The inaugural Inter-Provincial Championship was won by the Leinster Lightning, who clinched the title with one match to spare. Despite falling just four runs short of victory in their opening match, they then won their next two games before closing with a hard-fought, high-scoring draw against Northern Knights in the last game of the year at Waringstown.
The Inter-Provincial Series has been funded at least partly by the International Cricket Council via their Targeted Assistance and Performance Programme (TAPP).
