An election to all 28 seats on Clare County Council took place on 24 May 2019 as part of the 2019 Irish local elections. Councillors were elected for a five-year term of office from 5 local electoral areas (LEAs) on the electoral system of proportional representation by means of the single transferable vote (PR-STV).
Following a recommendation of the 2018 Boundary Committee, the boundaries of the LEAs in County Clare were altered from those used in the 2014 election. Its terms of reference required no change in the total number of councillors but set a maximum LEA size of seven councillors, whereas in 2014, the West Clare LEA had eight. Other changes were necessitated by population shifts revealed by the 2016 census.
