2023 Southend-on-Sea City Council election

The 2023 Southend-on-Sea City Council election was held on 4 May 2023 to elect members of Southend-on-Sea City Council in England. It coincided with local elections across the United Kingdom.

The council is elected by thirds, so a single member will be elected from all 17 wards to a term of four years. The seats elected at this election were last contested in 2019.

Prior to the election the council was under no overall control, being run by a Labour, Liberal Democrat and independent coalition. Following the election the council remained under no overall control, but the Conservatives were able to form a minority administration with support from some of the independent councillors.

Council composition
In the 2022 election, the Conservative Party and the Independents lost seats while Labour and the Liberal Democrats gained seats. While the Conservative were the largest party, the council was run by a Labour-led coalition along with the Liberal Democrats and Independents. Since then one Labour and one Independent councillor left their groups and formed a new group called Residents First.

Ward results
Results of the City Council election were released by Southend-on-Sea City Council on 5th May 2023.

Seat changes are compared to the 2019 election and do not take into account interim changes due to by-elections or defections.
