The Irish International or Irish Open in badminton is an international open held in Ireland since 1902 and is thereby one of the oldest badminton tournaments in the world. It was however interrupted by the two World Wars. This tournament is currently a part of the European Badminton Circuit and takes place at the end of November every year as part of the home nations loop of international tournaments that include the Scottish Open and the Welsh Open in consecutive weeks. The tournament for most part and in recent years has been an International Challenge rated event. The recent exception was in 2012, 2017 & 2018 when the tournament was downgraded to International Series due to funding. Recent editions have been held in the Baldoyle Badminton Centre except for 2007 and 2011 tournaments which were held in Lisburn, Northern Ireland.
