Middlesbrough Council, also known as Middlesbrough Borough Council, is the local authority for the Borough of Middlesbrough in North Yorkshire, England. Since 1996 the council has been a unitary authority, being a district council which also performs the functions of a county council. Following the 2023 local elections, Labour has held majority control of the council, which meets at the Town Hall. It is led by the directly-elected Mayor of Middlesbrough (Chris Cooke since 2023). The council is a member of the Tees Valley Combined Authority.

The town of Middlesbrough had been incorporated as a municipal borough in 1853. When elected county councils were established in 1889, Middlesbrough was considered large enough for its existing council to provide county-level services, and so it was made a county borough, independent from the new North Riding County Council, whilst remaining part of the North Riding of Yorkshire for ceremonial purposes.

The original borough of Middlesbrough was abolished in 1968, merging with several neighbouring authorities to become the County Borough of Teesside. That proved to be a short-lived local authority, being abolished just six years later when a new borough of Middlesbrough was created on 1 April 1974 under the Local Government Act 1972. The new borough covered the wards from Teesside which generally corresponded to both the pre-1968 borough and the former parishes of Hemlington, Marton and Stainton (which had all been abolished and absorbed into Teesside in 1968), plus the parish of Nunthorpe from the Stokesley Rural District. The re-created borough was a lower-tier district, being one of four districts within the new county of Cleveland. The county council provided county-level functions.

Cleveland County Council was abolished in 1996 following the Banham Review and the borough council took over county-level functions, in effect restoring Middlesbrough to the powers it had held prior to 1968 when it had been a county borough. The way the 1996 change was implemented was to create a new non-metropolitan county of Middlesbrough covering the same area as the existing borough, but with no separate county council; instead the existing borough council took on county functions, making it a unitary authority. At the same time the borough was transferred for ceremonial purposes to North Yorkshire, but as a unitary authority it has always been independent from North Yorkshire Council.

The council calls itself Middlesbrough Council, although the longer name Middlesbrough Borough Council is also sometimes used. It provides both county-level and district-level services. There are two civil parishes in the borough at Nunthorpe and Stainton and Thornton which form a second tier of local government for their areas; while the rest of the borough is unparished.

Since 2016, the council has been a member of the Tees Valley Combined Authority.

The council has been under Labour majority control since the 2023 election.
