Carlow–Kildare was a parliamentary constituency represented in Dáil Éireann, the lower house of the Irish parliament or Oireachtas from 1937 to 1948. The constituency elected 4 deputies (Teachtaí Dála, commonly known as TDs) to the Dáil, on the system of proportional representation by means of the single transferable vote (PR-STV).

The constituency was created for the 1937 general election under the Electoral (Revision of Constituencies) Act 1935, replacing the old Carlow–Kilkenny and Kildare constituencies.^[1]

Under the Electoral (Amendment) Act 1947, the constituency was abolished, and the Carlow–Kilkenny and Kildare constituencies were re-created for the 1948 general election.^[2]

The constituency covered all of County Kildare, and most of County Carlow.^[1] Carlow–Kildare's boundaries were defined by the 1935 Act as:

"The administrative County of Kildare.

The administrative County of Carlow except the portion thereof which is comprised in the County Constituencies of Wicklow and Wexford."^[1]

The Act defines the parts of Carlow in the Wicklow constituency as:

"The district electoral divisions of:

Clonmore, Hacketstown, Haroldstown, Kineagh, Rahill, Rathvilly, Tiknock and Williamstown in the administrative County of Carlow."^[1]

The parts of Carlow in the Wexford constituency are defined as:

"The district electoral divisions of:

Ballyellin, Ballymurphy, Borris, Coonogue, Corries, Glynn, Killedmond, Kyle, Marley, Rathanna, Sliguff and Tinnahinch in the administrative County of Carlow."^[1]
