Sing Ireland was established in 1980 to promote and develop choral singing in Ireland.

Sing Ireland (Previously Association of Irish Choirs (AOIC)) was established in 1980 by Dr Geoffrey Spratt and Aiveen Kearney to promote and develop choral singing in Ireland. Operating under the name Cumann Náisiúnta na gCór, AOIC ran training courses, established and ran the Irish Youth Choir, published music, and created a community of choral practitioners right across the country.

Now based in the Irish World Academy of Music and Dance at the University of Limerick, Sing Ireland still operates its key programmes (Annual Choral Conducting Summer School, the Irish Youth Choir), it embraces collective singing of all types and offers training to teachers and musicians.

In addition, Sing Ireland has become involved in the development of a number of initiatives as part of its mission. These include the National Choral Singing Week to promote the positive mental health benefits of collective singing and the Dawn and Dusk Choruses to encourage greater participation in choral singing among older people.
