This is a list of representative peers elected from the Peerage of Ireland to sit in the British House of Lords after the Kingdom of Ireland was brought into union with the Kingdom of Great Britain. No new members were added to the House after 1919, due to the creation of the Irish Free State, however, the already sitting members continued to remain part of the House, with the last member dying in 1961.

Once elected, peers held their seats for life.^{[n 1]} Some of these peers were granted a title in the Peerage of the United Kingdom which gave them a hereditary seat in the House of Lords. These peers also remained as representative peers and were not replaced until their deaths.
