K2 is an adults only, fully residential convention held in Killarney in Co. Kerry, Ireland.
From 2000 - 2008 the con was held in the Killarney Country Club. In 2009 the con moved to Old Killarney Village.
K2 is different to other Irish Gaming Conventions in that it has no formal timetable. Instead it operates on the basis that "everyone brings a game" and the convention provides space to play them in.
