2019 Dún Laoghaire–Rathdown County Council election
A Dún Laoghaire–Rathdown County Council election was held in Dún Laoghaire–Rathdown in Ireland on 24 May 2019 as part of that year's local elections. Forty councillors were elected for a five-year term of office from six local electoral areas (LEAs) by single transferable vote.

Following a recommendation of the 2018 Boundary Committee, the boundaries of the LEAs were altered from those used in the 2014 elections. Its terms of reference required no change in the total number of councillors but set a lower maximum LEA size of seven councillors, requiring a change to the eight-seat Dún Laoghaire LEA. Other changes were necessitated by population shifts revealed by the 2016 census.

Uniquely after 2019 Dún Laoghaire-Rathdown became Ireland's first 50:50 gender-neutral Council. Fine Gael remained the largest party gaining an additional 2 seats while seeing a slight reduction in vote-share. Fianna Fáil lost a seat in Stillorgan to return 7 in total and saw a slight reduction in vote share. The main winners in Dún Laoghaire were the Greens who won 6 seats and saw all 6 of their candidates elected in the process. They topped the poll in 4 of the 6 LEAs. Labour gained a seat in Dun Laoghaire but lost seats in Stillorgan and Glencullen-Sandyford to reduce their numbers to 6 seats overall. Solidarity-People Before Profit lost a seat in Dún Laoghaire to only return with 2 seats while Sinn Féin had a terrible election losing all 3 of their seats.
