Coill Dubh (Irish pronunciation: [ˌkəil̠ʲ ˈd̪ˠʊw]; meaning "black wood"[5]), also known as Blackwood,[1] is a town in Ireland in northern County Kildare, at the junction of the R403 and R408 regional roads, about 40 km (25 mi) from Dublin.

It was one of the fastest growing urban area in Ireland between the 2016 and 2022 census, with its population doubling from 746 to 1,476.

[1][2] The village is home to Coill Dubh GAA club, which has won the Kildare Senior Hurling Championship eleven times.

The town was established in 1952 on the townland of Blackwood ("Coill Dubh" is an Irish translation), just off the R403 between Prosperous and Timahoe to accommodate workers on the Bord na Mona works supplying a peat fired power station in Allenwood.

[6] It replaced earlier temporary workers camps at Killinthomas, Mucklon and Timahoe, with 160 houses and four shops.
