The Metropolitan Borough of Walsall is a metropolitan borough in the West Midlands, England. It is named after its largest settlement, Walsall, but covers a larger area which also includes Aldridge, Bloxwich, Brownhills, Darlaston, Pelsall and Willenhall.

The borough had an estimated population of 254,500 in 2007.

The borough was created on 1 April 1974 under the Local Government Act 1972. It is bounded on the west by the City of Wolverhampton, the south by the Metropolitan Borough of Sandwell, to the south east by the City of Birmingham, and by the Staffordshire districts of Lichfield, Cannock Chase and South Staffordshire to the east, north and northwest respectively. Most of the borough is highly industrialised and densely populated, but areas around the north and east of the borough are open space.

Prior to 1966, the area that would later become the metropolitan borough of Walsall was governed by five smaller local authorities:

The four urban districts were all within the administrative county of Staffordshire, in a two-tier structure with Staffordshire County Council providing county-level services. Walsall itself was a self-governing county borough, independent from the county council, but was still deemed to be part of Staffordshire for ceremonial purposes.

A review of local government in the West Midlands area was carried out under the Local Government Act 1958, culminating in the West Midlands Review Order 1965, which merged many of the districts in the area with effect from 1 April 1966. Darlaston and Willenhall were both absorbed into the county borough of Walsall, whilst the two urban districts of Brownhills and Aldridge merged to become Aldridge-Brownhills Urban District. At the same time, there were also more minor boundary adjustments with neighbouring areas around the edges of the new districts.

The new arrangements were relatively short-lived. Under the Local Government Act 1972, local government in the area was reviewed again, with Walsall County Borough and Aldridge-Brownhills Urban District merging to become the Metropolitan Borough of Walsall on 1 April 1974. On the same date the area became part of the new metropolitan county of West Midlands. For the next twelve years there was a two-tier structure in place, with West Midlands County Council providing higher county-level services. The county council was abolished in 1986.

There were adjustments to some of the boundaries between Walsall and its neighbours in 1994.
