Derby City Council elections are held every four years to elect members of Derby City Council, the local authority for the unitary authority of Derby in Derbyshire, England. Since the last boundary changes in 2023, 51 councillors have been elected from 18 wards. Prior to 2023 elections were held three years out of every four, with a third of the council elected each time.
The by-election was called after former Conservative councillor Richard Smalley was jailed for giving a false address.
