The Borough of Blackpool is a unitary authority area with borough status in the ceremonial county of Lancashire, North West England. It is named after the seaside town of Blackpool but covers a wider area which includes Anchorsholme, Bispham, Layton, Marton and Squires Gate, as well as the suburbs of Grange Park, North Shore, South Shore and Starr Gate. The borough also forms the core of the wider Blackpool conurbation.

The borough is bordered to the north and north-east by the Borough of Wyre (including Fleetwood, Cleveleys, Thornton and Poulton-le-Fylde), and to the south and south-east by Borough of Fylde (including Lytham St Annes), both of which are non-metropolitan districts in Lancashire. The western boundary is the Irish Sea coast. Surrounding districts form part of the Blackpool Urban Area which covers all the unitary authority area.

Blackpool was a municipal borough until 1889 when it became a county borough, on 1 April 1974, under the Local Government Act 1972, the county borough of Blackpool was reconstituted as a non-metropolitan district with the same boundaries as the county borough. Until 1998, Blackpool was administered as part of Lancashire County Council which was based in Preston. After the creation of unitary authorities by the government, Blackpool and Blackburn were successful in gaining their own right to govern independent from the county council. Blackpool gained unitary authority status, as did Blackburn and it was renamed "Blackburn with Darwen". As of 2021 these are the only two unitary authorities in Lancashire although they remain part of Lancashire for ceremonial purposes.
