The boundary between Cork city and County Cork, under the local jurisdiction of Cork City Council and Cork County Council respectively, was changed in mid 2019 when the Local Government Act 2018 came into force after the 2019 local elections, with the city area quadrupling in size. Its implementation followed the Cork Local Government Review, a 2015 review by the Cork Local Government Committee which recommended merging the two councils into a single "super-council". The recommendation was unpopular within the city and in 2017, after a review, it was dropped in favour of extending the city boundary into territory of the county. This alternative was not approved by county council, which meant the Fine Gael-led government was obliged to pass an Act of the Oireachtas to effect it.
