Kildare County Council (Irish: Comhairle Contae Chill Dara) is the local authority of County Kildare, Ireland. As a county council, it is governed by the Local Government Act 2001. The council is responsible for housing and community, roads and transportation, urban planning and development, amenity and culture, and environment. The council has 40 elected members. Elections are held every five years and are by single transferable vote. The head of the council has the title of Cathaoirleach (chairperson). The county administration is headed by a chief executive, Sonya Kavanagh. The county town is Naas.

The County Council was formed in 1899 under the Local Government (Ireland) Act 1898. It was originally based at Naas Courthouse but, after a major fire in the courthouse, moved to the former St Mary's Fever Hospital in the late 1950s.^[1] By late 1990s, the old hospital buildings were in poor condition, and the county council identified the former Devoy Barracks site as its preferred location for new facilities.^[2] It moved to Áras Chill Dara on the site of the old barracks site in 2006.^[2]

Kildare County Council has three representatives on the Eastern and Midland Regional Assembly who are part of the Eastern Strategic Planning Area Committee.^[3][4]

Members of Kildare County Council are elected for a five-year term of office on the electoral system of proportional representation by means of the single transferable vote (PR-STV) from multi-member local electoral areas (LEAs).

County Kildare is divided into municipal districts and LEAs, defined by electoral divisions.^[5]

The following were elected at the 2019 Kildare County Council election, under the boundaries which existed at the time. ^[6]
