Carbury (Irish: Cairbre),[1] also formerly spelt "Carbery", is a rural community and a village 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, Ticknevin and Killina along the Grand Canal (Ireland).

He and his brothers were the keepers of the well at the foot of the hill, (now Trinity Well at Newberry Hall, Carbury, County Kildare) which was associated with the gift of wisdom.

According to legend, the curious Bóinn was swept along with the rushing waters and drowned, and thus the River Boyne - an embodiment of her spirit - was created.

They were the Ó Ciardha sept of the Southern Uí Néill (anglicised Carey, Carry and Keary) who were the Lords of Carbury mentioned in the Annals of the Four Masters in 952.

The motte on the top of the hill behind the current castle was probably built by Meiler FitzHenry who was granted the area by Strongbow.
