The Irish Guild of Organists and Choristers is an independent interdenominational learned society, composed of church musicians and others interested in church music. It is based on the medieval concept of the Guild, which was a group of professionals who gathered together for working and fraternal reasons.

The aims of the Guild are to raise awareness of the history of Church music and to promote the highest standards in its practice. The Guild also exists to encourage members in their spiritual lives, and to provide a means whereby they can share experience and resources with other musicians.

Individual membership of the Guild was available at two levels: Associate and Fellow. Membership brings the entitlement to use postnominal letters and to wear academic dress. This shall not be misconstrued as representing an academic or professional qualification. Corporate Membership was available to choirs and other bodies who subscribe to the aims of the Guild.

The Guild is somewhat dormant and not accepting new members.
