Kilmacduagh (Irish: Cill Mhic Dhuach, meaning "Church of Duach's son") is a small village in south County Galway, near Gort, in Ireland. It is best known for Kilmacduagh monastery, seat of the Diocese of that name. The diocese is now part of the Diocese of Galway and Kilmacduagh in the Roman Catholic Church and in the Diocese of Limerick and Killaloe in the Church of Ireland. The former cathedral is now a ruin.
