The 2021 Sheffield City Council election took place on 6 May 2021 to elect members of Sheffield City Council in England, as part of the nationwide local elections. The election was originally due to take place on 7 May 2020, but was postponed due to the COVID-19 pandemic.[2] One seat from each ward was up for election.
A delayed local governance referendum (held under the provisions of the Localism Act 2011) also took place at the same time as the local elections.
Three Labour seats had become vacant, and left unfilled since 2019. Michelle Cook (Broomhill & Sharrow Vale) resigned in February 2020, Olivia Blake (Walkley) resigned in March 2020 and Peter Rippon (Richmond) died in December 2020.
The result had the following consequences for the total number of seats on the Council after the elections:
There were two seats elected due to a vacancy resulting from the death of Labour councillor Peter Rippon a year earlier. Polling the highest number of votes, David Barker won the three-year term (reduced from four years due to the delayed elections), and Mike Drabble won the two-year term (reduced from three years).
