2021 Manchester City Council election

Elections to Manchester City Council were held on 6 May 2021, as part of the 2021 United Kingdom local elections. They were originally scheduled for 2020 but were suspended for a year, due to the COVID-19 pandemic. In 2019 Labour had retained its majority on the council, with 93 seats, with the Liberal Democrats led by former MP John Leech increasing the number of opposition councillors to three, but this had fallen back to two in March 2021 when Councillor Greg Stanton defected to the Labour Party.

Background and campaign
The following councillors, last elected in 2018, did not stand for re-election:
 * Labour: Kelly Simcock (Didsbury East), Nigel Murphy (Hulme, deselected), Bernard Stone (Levenshulme), Carl Ollerhead (Moston, suspended by party in June 2020), Maddy Monaghan (Sharston), Mary Watson (Whalley Range).

One councillor from 2018 to 2021, Labour's Emma Taylor, had previously been elected in Ancoats and Beswick and stood this time in a different ward, Sharston.

Two by-elections were outstanding and were held alongside the scheduled elections of 2021: one for the seat of councillor Sue Murphy (Labour, Brooklands, elected 2019), who had died in April 2020, and the other for that of Ken Dobson (Independent, Clayton and Openshaw, elected at a by-election in February 2020), who had resigned from the council in October 2020.

Result
Summary change in vote share compared to the 2019 election. Change in number of seats compared to the composition of the council immediately before the election. Where multiple seats were contested in the same ward due to vacancies the results have been normalised.
