Nottinghamshire County Council is the upper-tier local authority for the non-metropolitan county of Nottinghamshire in England. The non-metropolitan county is smaller than the ceremonial county; the non-metropolitan county excludes the city of Nottingham, with Nottingham City Council being a unitary authority, independent from the county council. The county council comprises 66 councillors, elected from 56 electoral divisions every four years. The council's headquarters are at County Hall in West Bridgford. The council has been under Reform UK majority control since the 2025 election.
The council is a constituent member of the East Midlands Combined County Authority.
