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.
The 3rd United Kingdom Parliament was elected between 29 October and 17 December 1806, as at this period the exact date for the election in each constituency was fixed by the Returning Officer. The Parliament first assembled on 13 December, for a maximum duration of seven years from that date. It was dissolved on 29 April 1807 (a length of four months and sixteen days - the shortest UK Parliament ever).
