The Royal Society of Antiquaries of Ireland (RSAI) is a premier learned society dedicated to the preservation, examination, and study of Ireland's ancient monuments, history, and cultural heritage. Established in 1849, the Society fosters public understanding of the material and literary past, supports historical and archaeological research, and maintains a significant library and archive. It actively engages the community through a programme of lectures, excursions, and the publication of a peer-reviewed academic journal, while managing the historic Society House in Dublin.
