Limerick County is a parliamentary constituency that has been represented in Dáil Éireann, the lower house of the Irish parliament or Oireachtas, since the 2016 general election. The constituency elects 3 deputies (Teachtaí Dála, commonly known as TDs) on the system of proportional representation by means of the single transferable vote (PR-STV).

The Constituency Commission proposed in its 2012 report that at the next general election a new constituency called Limerick County be created from territory then in the constituencies of Kerry North–West Limerick and Limerick.^[1] This was adopted under the Electoral (Amendment) (Dáil Constituencies) Act 2013 which came into effect at the 2016 general election. The Constituency Review Report 2023 of the Electoral Commission recommended that no change be made at the next general election.^[2]

For the next general election, the Electoral (Amendment) Act 2023 defines the constituency as:^[3]

"The city and county of Limerick, except the parts thereof which are comprised in the constituency of Limerick City."
