[2] Today, some of the wealthiest areas in Ireland, such as Malahide,[3] Howth,[4] Clontarf,[5] and Castleknock, lie north of the river.

[7] James Joyce set several of the Dubliners stories on the Northside, reflecting his childhood sojourns in Drumcondra and Fairview.

The soap opera Fair City is set in Carrigstown, a fictional suburb within Dublin's Northside.

[8] The Northside includes Dublin city centre north of the Liffey, of whose many streets some are noted below, and districts such as Smithfield and Summerhill.

[9] Another quirk of the postal district system on the Northside is that the town of Clonee in Dublin's neighbouring County Meath has the Eircode of D15.

State bodies based on the Northside include Met Éireann (the national meteorological office), the Central Fisheries Board, Enterprise Ireland (the national enterprise and trade board), the National Standards Authority of Ireland, Sustainable Energy Authority of Ireland, the Marine Institute, the Department of Defence, the Department of Education, and the Department of Housing, Local Government and Heritage.
