# Laois–Offaly (Dáil constituency)

Laois–Offaly (formerly King's County–Queen's County, Leix–Offaly and Laoighis–Offaly) was a parliamentary constituency which was represented in Dáil Éireann, the house of representatives of the Oireachtas (the legislature of Ireland), from 1921 to 2016 and again from 2020 to 2024. The constituency elected deputies (Teachtaí Dála, commonly known as TDs) on the system of proportional representation by means of the single transferable vote (PR-STV).

## History and boundaries

Laois–Offaly was created under the Government of Ireland Act 1920 as King's County–Queen's County (the respective names of County Offaly and County Laois 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, which came into effect for the 2020 general election.
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. Each new constituency would elect 3 deputies. These changes took effect for the 2024 general election under the Electoral (Amendment) Act 2023.
