2019 Longford County Council election

An election to all 18 seats on Longford County Council was held on 24 May 2019 as part of the 2019 Irish local elections. County Longford was divided into 3 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).

The votes were counted in St. Mary's Community Centre, Edgeworthstown. Counting began on Saturday 25 May, and ended at 9.25 p.m. on Tuesday 28 May when returning officer Nora O'Farrell declared the last 4 councillors to be elected in the Ballymahon LEA, where there had been a recount.

Boundary review
Following the recommendations of the 2018 LEA boundary review committee, there was a revision to the LEAs used at the 2014 elections, with an adjustment in boundaries and the transfer of one seat from Granard to Longford LEA.
