Thebarton (/ˈθɛbərtən/ THEB-ər-tən) is a suburb of the city of Adelaide, South Australia. 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 are actually in the adjoining suburb of Torrensville, including 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.
The Thebarton campus of the University of Adelaide, also known as Adelaide University Research Park, occupies a complex of former industrial buildings in the northeastern corner of the suburb.
