Laois–Offaly (formerly King's County–Queen's County, Leix–Offaly and Laoighis–Offaly) is a parliamentary constituency which is represented in Dáil Éireann, the lower house of the Irish parliament or Oireachtas. The constituency elects 5 deputies (Teachtaí Dála, commonly known as TDs) on the system of proportional representation by means of the single transferable vote (PR-STV). It was previously a constituency from 1921 to 2016.

Laois–Offaly was created under the Government of Ireland Act 1920 as King's County–Queen's County (the official names of the counties before independence). The two counties were combined in a single four-member constituency for the House of Commons of Southern Ireland. It was known in the Dáil as Leix–Offaly, and first used for the 1921 general election to the Second Dáil. The Sinn Féin candidates elected unopposed preferred to sit in the Second Dáil (1921–22). It was used at every subsequent general election until 2011. It was abolished at the 2016 general election, and was replaced by the new constituencies of Laois and Offaly.

It was re-established by the Electoral (Amendment) (Dáil Constituencies) Act 2017, It replaced the constituencies of Laois and Offaly, which came into effect at the 2020 general election, where it was defined as:^[1]

"The county of Laois except those parts that are comprised within the constituency of Kildare South,

and the county of Offaly except those parts that are comprised within the constituency of Kildare South."

In August 2023, the Electoral Commission published its review of constituency boundaries in Ireland, which recommended that the constituency of Laois–Offaly be abolished, with the creation of two new three-seat constituencies: Laois and Offaly.^[2] Each new constituency would elect 3 deputies. These changes would commence at the next general election.
