Irish Evangelical Society (IES), was an organisation founded in 1814 to promote the Protestant faith in Ireland. It was initially founded in London. Its aim was to support preachers and priests of the Reformed faith outside the established Church of Ireland. It was supported by a number of Evangelical members of the Church of Ireland, as well as members of the society in England. As a result, it supported Independent Ministers, priests and Chapels. It became closely aligned to the Congregationalists, and was pretty much absorbed by Congregational Union of Ireland by 1899.
