Carbury (Irish: Cairbre), also formerly spelt “Carbery”, is an expanding rural community in north-west County Kildare, Ireland. It is situated on the R402 regional road between Enfield and Edenderry, near the border with County Offaly, and includes the smaller hamlets of Derrinturn, Allenwood, Ticknevin and Killina along the Grand Canal (Ireland). The source of the River Boyne is located just north of the village.

Carbury Hill (OS Ref (IE): N685348 / Sheet: 49. Latitude: 53° 21′ 32.33″ N and Longitude: 6° 58′ 15.71″ W) is close to the source of the River Boyne that runs by Brú na Bóinne. There are the two barrows on the hill that are dated to the Bronze Age, a motte and a tower house indicating multiple usage and settlement over time.[1] The hill was at the centre of the ancient territory known as Cairbre Uí Chiardha[2](which may still be seen on signposts in the area) of the Ó Ciardha sept of the Southern Uí Néill (anglicised Carey and Keary) who were Lords of Carbury, first mentioned in the Annals of the Four Masters in 952.[3] It was also a camping site used by the Irish during the United Irishmen Rebellion of 1798.
