The 2023 election to Derry City and Strabane District Council was held on 18 May 2023, alongside other local elections in Northern Ireland, two weeks after local elections in England. The Northern Ireland elections were delayed by 2 weeks to avoid overlapping with the coronation of King Charles III.

The election returned 40 members to the council via Single Transferable Vote.
