2023 Oldham Metropolitan Borough Council election

The election took place using the plurality block voting system, a form of first-past-the-post voting, with each ward being represented by three councillors. The candidate with the most votes in each ward will serve a four year term ending in 2027, the second-placed candidate will serve a three year term starting in 2026 and the third-placed candidate will serve a one year term ending in 2024.^[5]

All registered electors (British, Irish, Commonwealth and European Union citizens) living in Oldham aged 18 or over were entitled to vote in the election. People who lived at two addresses in different councils, such as university students with different term-time and holiday addresses, were entitled to be registered for and vote in elections in both local authorities. Voting in-person at polling stations took place from 07:00 to 22:00 on election day, and voters were able to apply for postal votes or proxy votes in advance of the election.

Asterisks denote incumbent councillors seeking re-election.

Since the elections, the three elected councillors from Hollinwood were suspended from the Conservative Party^[7] in November 2023, forming the "Oldham Group" party. This has caused the composition of the council to change in November 2023, making the Liberal Democrats the official opposition.
