Dublin City was an Irish borough constituency in the House of Commons of the United Kingdom of Great Britain and Ireland. It comprised the city of Dublin in the county of Dublin, and was represented by two Members of Parliament from its creation in 1801 until 1885.
In 1885, Dublin City was split into four divisions which were separate single member constituencies: Dublin College Green, Dublin Harbour, Dublin St Stephen's Green and Dublin St Patrick's.
The city of Dublin was accounted a county of itself, although it remained connected with County Dublin for certain purposes. A Topographical Directory of Ireland, published in 1837, describes the parliamentary history of the city:
The boundary was defined in the Parliamentary Boundaries (Ireland) Act 1832 as:
From 1832 (when registers of electors were first prepared) a turnout figure is given, for the percentage of the registered electors who voted. If the number of registered electors eligible to take part in a contested election is unknown, then the last known electorate figure is used to calculate an estimated turnout. If the numbers of registered electors and electors taking part in the poll are known, an exact turnout figure is calculated. In two member elections (in which an elector could cast one or two votes as he chose), where the exact number of electors participating is unknown, an estimated turnout figure is given. This is calculated by dividing the total number of votes cast by two. To the extent that electors used only one of their votes the estimated turnout figure is an underestimate.
On petition, Harty and Perrin were unseated, causing a by-election.
West's death caused a by-election.
On petition, the poll was amended and 92 votes were struck off Reynolds, although this did not cause him to be declared unelected.
Guinness' death caused a by-election.
Following the election, a publication was printed listing the names of those who had voted, and for whom. The listing was categorised by the seventeen individual wards and districts of Dublin, and a further category solely reserved for the Freemen of Dublin. A similar publication was produced for the voters in the wider County of Dublin.
On petition, Guinness was unseated.
