The Peerage of Ireland is the term used for those peers created by British monarchs in their capacity as Lord or King of Ireland. Before 1801, Irish Peers had the right to sit in the Irish House of Lords, but after the Union in 1801, Irish peers, like those of Scotland, only elected representative peers - twenty-eight in number - to the House of Lords (see List of Irish representative peers). This practice ended with the creation of the Irish Free State in 1922. Irish Peerages continued to be created for some time after 1801 as a way of creating peerages which did not grant a seat in the House of Lords. The last to be granted was one for George Curzon in 1899.
In the following table of Irish peers, higher or equal titles in the other peerages are listed. Also, if the peer holds a lower title in the Peerages of England, Great Britain, or the United Kingdom, and therefore sat by such a peerage in the House of Lords, such a lower title is listed.
