The Irish Georgian Society is a membership organisation whose purpose is to promote awareness and the protection of Ireland's architectural heritage and decorative arts. These aims are achieved through the activities of its membership and through its conservation and education programmes.

The Society has an international membership of 2,000. Based in Dublin, we have active regional Chapters in Cork, Birr and Limerick and, in the UK, a thriving London Chapter. Our strong United States membership has its headquarters in Chicago and Chapters in Boston, New York and Palm Beach. The benefits of membership include: an annual members' magazine; participation in the Society’s events programme; the Society’s annual journal Irish Architectural and Decorative Studies; and free or concessionary access to selected heritage properties in Ireland.

The Irish Georgian Society was founded in 1958 by the Hon. Desmond Guinness and Mariga Guinness for the protection of buildings of architectural merit in Ireland. Many fine houses have been saved through their enthusiasm and commitment, and the dedication of members and supporters. The current President is Sir David Davies.
