The (Reformed Romanist) Priests' Protection Society was an Anglican organisation in Ireland in the nineteenth century which sought to encourage and support Roman Catholic clergy who defected from the Catholic church and assist them in becoming members and priests of the Church of Ireland. The also supported the re-educating of these converts.
The organisation was critical of the Catholic Church's ethos and practice, and also critical of the government for policies such as the Maynooth Grant.
The organisation was founded on 5 May 1844 when "the Rev. Solomon Frost renounced Popery in St. Audoen's Church, Dublin". The chief patron was the Earl of Roden, a figure in the evangelical Protestant Second Reformation. Others who supported the Society included Irish Lords, members of the Church of Ireland, and Church of England clergy. They had offices in Sackville (O'Connell) Street, Dublin, with lecture and library facilities. The society printed and distributed pamphlets articulating its views.
