Kilbarrack (Irish: Cill Bharróg, meaning 'Church of St. Berach or of young Barra') is a residential suburb of Dublin, Ireland, running inwards from the coast, about 8 km (5.0 mi) from the city's centre.

Kilbarrack is accessible from the coast road and the Tonlegee Road, by its own station on the (DART) Dublin Area Rapid Transit suburban rail system (as well as from Raheny and Howth Junction stations), and by bus routes N6 from Finglas, H3 to Howth or the city centre and H2, to the city centre or Portmarnock and Malahide.

[2] Kilbarrack is an old district, whose name can be found on maps and sea charts, many held at Dublin City Archive, going back several hundred years.

The district is crossed by one of Dublin's small waterways, the Kilbarrack Stream or Donough Water, which enters the sea in two branches.

There is a major Health Services Executive centre, and, at the boundary with Raheny and Donaghmede, a municipal fire station and practice yard.
