A Longford County Council election was held in County Longford in Ireland on 24 May 2019 as part of that year's local elections. All 18 councillors were elected for a five-year term of office from 3 local electoral areas (LEAs) by single transferable vote. The 2018 LEA boundary review committee kept the LEAs used in the 2014 elections, adjusting their boundaries and transferring one seat from Granard to Longford LEA. The new boundaries were enacted by Statutory Instrument (SI) S.I. No. 625/2018.
