The 2018 Inter-Provincial Championship was the sixth edition of the Inter-Provincial Championship, a first-class cricket competition played in Ireland. It was held from 1 May to 6 September 2018.[1] It was the second edition of the competition to be played with first-class status. Leinster Lightning were the defending champions.[2] The venue for the opening fixture, originally scheduled to take place at Oak Hill Cricket Club Ground, was moved to Pembroke Cricket Club, due to poor weather.[3]
Seventeen of Ireland's international players took part in the opening fixture of the tournament, ahead of Ireland's first Test match, which was played against Pakistan on 11 May 2018.[4] [5]
North West Warriors won the tournament, following the conclusion of the fifth match of the competition.[6] They beat Northern Knights by 140 runs to give them an unassailable lead.[6] It was the first time that a side other than Leinster Lightning had won the tournament.[6]
