The 2015 GAA Interprovincial Championships (known also as the Railway Cup) was a senior GAA competition in which all 4 provinces of Ireland were due to compete in Gaelic football and hurling tournaments. The provincial squads are made up of players from county panels in each respective province. Due to adverse weather conditions, the 2015 inter-provincials did not take place.
Connacht were the reigning football champions whilst Leinster were the reigning hurling champions.
