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.^[1] The report proposed changes to the constituencies of Ireland so as to reduce the total number of TDs from 166 to 158.^[2]

The constituency was established by the Electoral (Amendment) (Dáil Constituencies) Act 2013.^[3] 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.^[4][5]

The Electoral (Amendment) Act 2023 defines the constituency as:^[6]

"In the city of Dublin, the electoral divisions of:

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;
