# Dublin Bay North (Dáil constituency)

Dublin Bay North is a parliamentary constituency that has been represented in Dáil Éireann, the lower house of the Irish parliament or Oireachtas, since the 2016 general election. The constituency elects five deputies (Teachtaí Dála, commonly known as TDs). The method of election is proportional representation by means of the single transferable vote (PR-STV).

## History and boundaries

The Constituency Commission proposed in its 2012 report that at the next general election a new constituency called Dublin Bay North be created. The report proposed changes to the constituencies of Ireland so as to reduce the total number of TDs from 166 to 158.
The constituency was established by the Electoral (Amendment) (Dáil Constituencies) Act 2013. It incorporated the entirety of Dublin North-Central and most of Dublin North-East; with the transfer of an area around the village of Portmarnock from Dublin North-East into Dublin Fingal.
The Constituency Review Report 2023 of the Electoral Commission recommended that at the next general election Dublin Bay North be altered by the transfer of territory from Dublin Fingal and the transfer of territory to Dublin North-West.
The Electoral (Amendment) Act 2023 defines the constituency as:
       Ayrfield, Beaumont C, Beaumont D, Beaumont E, Clontarf East A, Clontarf East B, Clontarf East C, Clontarf East D, Clontarf East E, Clontarf West A, Clontarf West B, Clontarf West C, Clontarf West D, Clontarf West E, Edenmore, Grace Park, Grange A, Grange B, Grange C, Grange D, Grange E, Harmonstown A, Harmonstown B, Kilmore B, Kilmore C, Kilmore D, Priorswood A, Priorswood B, Priorswood C, Priorswood D, Priorswood E, Raheny-Foxfield, Raheny-Greendale, Raheny-St. Assam;
   and, in the county of Fingal, the electoral divisions of:
       Baldoyle, Balgriffin, Howth, Sutton.

### 2016 general election

The constituency was dubbed the "group of death" by media because of the large number and high profile of candidates, the close contest, and the protracted nature of the count.
