Cornelscourt (Irish: Cúirt an Choirnéil) is a small suburban area of South Dublin, situated between Cabinteely and Foxrock. It has a mostly commercial rather than residential character and is best known for being the site of Ireland’s first big-box store, a branch of Dunnes Stores.

Cornelscourt consists of the houses and shops on either side of a section of the bypassed Old Bray Road between the junction with the N11 to the East. Along this strip are: a petrol station, a well known pub called “The Magic Carpet” which contained one of Ireland’s first non-smoking lounges in a pub – the “Samuel Beckett” lounge, named after a former customer. Upstairs, there is a new art gallery and exhibition space, named the “Gallery Intermarium”, and there is also a 60 seat theatre named the “Dolmen Theatre” above the pub. There is a drama school called “Arclight”, an Indian Restaurant, a traditional fish and chip shop named “Aldos”, along with several other take-away food outlets. There is also a convenience store, a pharmacy named “Hiltons”, and the above-mentioned Dunnes Stores. The surrounding residential housing is laid out in suburban housing estates.
