This is a list of the MPs for Irish constituencies, who were elected at the 1806 United Kingdom general election, to serve as members of the 3rd UK Parliament from Ireland, or who were elected at subsequent by-elections. There were 100 seats representing Ireland in this Parliament. This was the second United Kingdom general election, as the House of Commons of the 1st Parliament was chosen from the members of the Parliament of Great Britain and the Parliament of Ireland and not by a popular election.
