Cabinteely (Irish: Cábán tSíle, meaning 'Sheila's cabin') is a suburb of Dublin's southside. It is in Dún Laoghaire–Rathdown, County Dublin, Ireland. The population of all electoral divisions labelled as Cabinteely was 15,864 as of the 2022 census.

Cabinteely lies around the crossroads of Johnstown Road / Brennanstown Road and the Old Bray Road, and on either side of the Stillorgan Dual Carriageway (N11), which is parallel to the Old Bray Road. The R827 road runs from Blackrock and terminates in Cabinteely.

Much of Cabinteely is parkland (Cabinteely Park and Kilbogget Park) or open countryside (around Laughanstown and Brennanstown).

Cabinteely borders Ballybrack, Carrickmines, Cherrywood, Cornelscourt, Deansgrange, Foxrock, Johnstown, Killiney and Loughlinstown.

The area has seen human activity since prehistoric times - there is a tomb known as Brennanstown Portal Tomb, Glendruid cromlech/dolmen, or The Druids' Altar near Cabinteely.

Excavations between 1957 and 1999 some 700m southeast of Cabinteely suggest that the area was of "considerable status and importance" from the 6th-7th centuries, with possible evidence of a church, ancillary buildings, possible workshops and a cemetery.

Anecdotal evidence suggests that Cabinteely grew up around a tavern (Irish: Cabán tSíle, meaning 'Sheila's Cabin') located at a crossroads on the main road linking Dublin with the South.^{[citation needed]}

Cabinteely sits at the meeting point of the three medieval civil parishes of Tully, Kill and Killiney, in the half-barony of Rathdown. The ruins of Kill Abbey/Grange Church are near Deansgrange. The modern suburb of Cabinteely is still split between these civil parishes.
