2019 Louth County Council election

An election to all 29 seats on Louth County Council was held on 24 May 2019 as part of the 2019 Irish local elections. County Louth was divided into 5 local electoral areas (LEAs) to elect councillors for a five-year term of office on the electoral system of proportional representation by means of the single transferable vote (PR-STV).

Boundary review
Following a recommendation of the 2018 LEA boundary review committee, the local electoral areas in County Louth were altered. The committee's terms of reference required a maximum number of councillors of 7 seats, which had been breached by the 10-seat Drogheda LEA used at the 2014 Louth County Council election. There were boundary adjustments in other LEAs to reflect by population shifts revealed by the 2016 census. The boundary committee recommended that Dundalk be designated a borough district. This was implemented in the initial statutory instrument, but reversed as being contrary to the terms of the Local Government Act 2001.

Overview
Following the elections Sinn Féin and Fianna Fáil emerged as the joint largest party with 7 seats. Sinn Féin lost 1 seat in Dundalk and 2 in Drogheda. Fianna Fáil gained a seat from Sinn Féin and also from the Green Party in Dundalk. Accounting for the defection of Kevin Callan after 2014, Fine Gael returned with 5 seats, a loss of 2 seats overall. The Labour Party increased their numbers by 1 seat to 3 by gaining another seat in Drogheda.

Kevin Callan won a seat in each of the 2 Drogheda LEAs. He chose to sit for Drogheda Urban. The casual vacancy was filled at a meeting of the council on 17 June 2019 by Declan Power, who had run for Fianna Fáil in 2019 but who had since quit the party.
