An election to all 31 seats on Cork City Council was held in Cork city in Ireland on 24 May 2019 as part of that year's local elections. Councillors were elected from five local electoral areas (LEAs) on the electoral system of proportional representation by means of the single transferable vote (PR-STV). This election coincided with an increase in the city area. Several outgoing members of Cork County Council, based in areas transferred to the city, stood for election to the city council. As well as the extension of all LEAs into the former county area, the former LEA of North Central was abolished and its area divided between North West and North East.
On the same day, a plebiscite was held under the Local Government Act 2019 on whether Cork City should have a directly elected executive mayor. Voters rejected the proposal in favour of retaining the existing ceremonial Lord Mayor of Cork, chosen annually by the councillors from among their number.
