TheBorough of Swindon is aunitary authority area withborough status inWiltshire, England. Centred onSwindon, it is the most north-easterly district ofSouth West England.
The first borough of Swindon was amunicipal borough, created in 1900 as a merger of the twourban districts of Old Swindon and New Swindon.[2]
In 1974, the borough ofThamesdown was created under theLocal Government Act 1972. Thamesdown covered the areas of the municipal borough of Swindon and the neighbouringHighworth Rural District (which had been created in 1894), which were both abolished at the same time.[3][4] Thamesdown was a lower-tiernon-metropolitan district, withWiltshire County Council being the higher-tier authority for the area. Thamesdown was givenborough status from its creation, allowing the chair of the council to take the title of mayor.[5]
On 1 April 1997 Thamesdown was made aunitary authority, making it administratively independent from Wiltshire County Council.[6] In June 1996, during the transition period to becoming a unitary authority, the council passed an order that the area would be renamed Swindon with effect from 1 April 1997 as well.[7] The former Thamesdown name and logo continued to be used by the municipal bus operator,Thamesdown Transport, until 2017 when it was sold and renamed to "Swindon's Bus Company".[8] Swindon remains part of theceremonial county of Wiltshire for the purposes oflieutenancy.[9]
The borough of Swindon encompasses an area forming the north east corner ofWiltshire and is bordered by two other counties,Gloucestershire (to the north) andOxfordshire (to the east).West Berkshire is also only a short distance from the borough's south-eastern frontier.The generally hilly landscape is sculpted by the upperThames guiding the northern border, small tributaries draining into the Thames, and theMarlborough Downs rising toward the south.

The borough encompasses the Swindon urban area and surrounding countryside to the north, east and south, including the town of Highworth. It comprises the former Swindon Municipal Borough and a further 18civil parishes:[10][11]
Since 1 April 2017 the entire Borough has been parished, following the establishment of West Swindon parish and the creation ofCentral Swindon North andCentral Swindon South[11] (styled by its parish council as South Swindon).[12][13] The two central parishes fall within the boundaries of the town and former municipal borough, divided along theGreat Western Main Line railway.
