An election to all 32 seats on Waterford City and County Council was held on 24 May 2019 as part of the 2019 Irish local elections. The City and County of Waterford was divided into 6 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).
Voters in Waterford also took part in a plebiscite on whether or not to establish the position of a directly elected mayor for the council under the Local Government Act 2019. The proposal was rejected by a narrow margin of 50.8% No to 49.2% Yes. Two other council also held plebiscites on directly elected mayors: Cork City rejected the proposal, and Limerick was the only one of the three to vote Yes.
Following the recommendations of the 2018 boundary review committee, there were significant changes to the LEAs in the 2014 election due to terms of references requiring a maximum of seven councillors in each LEA and changes in population revealed in the 2016 census.
