The Irish Go Association (IGA) promotes Go in Ireland, and is a member of both the International Go Federation and the European Go Federation. It organises club and tournament events as well as teaching sessions.
In 2001 the IGA and British Go Association ran the 45th European Go Congress in Dublin, which was attended by around 400 players.
The IGA was founded in 1989, by the merging of two Dublin clubs - Trinity College and Collegians Chess and Go Club. The Association is cross-border, having affiliated clubs in Northern and Southern Ireland. Its national championship has run every year since 1990.
