Thebarton (// THEB-ər-tən), formerly Theberton, is an inner-western suburb of Adelaide, South Australia in the City of West Torrens. The suburb is bounded by the River Torrens to the north, Port Road and Bonython Park to the east, Kintore Street to the south, and South Road to the west.
Many buildings and landmarks that bear the name of Thebarton were in the history municipality, the Town of Thebarton, which included most of the adjoining suburb of Torrensville. These include the Thebarton Oval, the Thebarton croquet and bowls club, Thebarton Theatre, and Thebarton Senior College. The historic Adelaide Gaol, nominally shown as being in Thebarton, and the adjacent Thebarton Barracks of the South Australia Police actually lie within the northwestern Adelaide Park Lands.
Prior to European settlement, the areas now known as Thebarton and Hindmarsh were called Karraundongga (meaning "red gum spear place") by the Kaurna people, who would craft spears from the red gum branches gathered on the banks of the Torrens there.
The suburb of Thebarton was named after the home of Colonel William Light, the first Surveyor-General of the colony of South Australia, where he lived with his de facto wife Maria Gandy and her brothers. Light named his home after Theberton Hall of Suffolk, England, where he was educated. The area was known as Theberton until approximately 1840, with the variant spelling now accredited to a typographical error, rather than a corruption of "The Barton", based on the Old English bere-tun, meaning "barley farm", as was thought for some time.
Colonel Light surveyed the town-acre as Section 1 and built Theberton Cottage towards the northern part of the area. The area was first subdivided for housing in February 1839, although it took a number of years for the housing to establish, Thebarton Post Office opening on 24 October 1850. By 1866 the population was estimated at around 450 people.
Thebarton has a significant Greek-Australian population and is the suburb with the largest Greek Australian population per capita in Australia. In fact, according to census data released by the Australian Bureau of Statistics in 2001, the suburbs of Thebarton and neighbouring Torrensville together are home to 4,471 Greek-Australians; i.e., 18.7 per cent of the total population.
Thebarton was part of the then largely rural District of West Torrens until 1883, when the residents of the more urban suburbs of Thebarton, Mile End and Torrensville successfully petitioned to become the Corporation of the Town of Thebarton.
In 1997 the Town of Thebarton re-amalgamated with the City of West Torrens.

Originally a private subdivision of section 46. Name of the house was taken from Colonel Light's English home - Theberton Hall. Thebarton was the first village laid out outside of the City of Adelaide. Available evidence suggests that the current spelling with a central "a" has arisen through a typographic error. Proposal in 1982 to alter the name to Theberton not approved by Geographical Names Board. Portion added in 1945.
- "Place names of South Autralia: T". State Library of South Autralia. The acceptance of Thebarton with an 'a' instead of an 'e' is credited to a typographical error and not the some time held view that it was a corruption of 'The Barton' based on the Old English bere-tun meaning 'barley farm'.
