Adelaide is a single-memberelectoral district for theSouth Australian House of Assembly. The 22.8 km² state seat of Adelaide currently consists of theAdelaide city centre includingNorth Adelaide and suburbs to the inner north and inner north east:Collinswood,Fitzroy,Gilberton,Medindie,Medindie Gardens,Ovingham,Thorngate,Walkerville, most ofProspect, and part ofNailsworth. The federaldivision of Adelaide covers the state seat of Adelaide and additional suburbs in each direction.

The electorate's name comes from the city which it encompasses, which is named after the British queenAdelaide of Saxe-Meiningen.

The six-seatmulti-memberelectoral district of City of Adelaide existed from 1857 to 1862.

The four-member electoral district of Adelaide was created by theConstitution Act Amendment Act, 1901 for the1902 election from the districts ofEast Adelaide,West Adelaide andNorth Adelaide; together with the three-memberPort Adelaide and five-memberTorrens, the three districts with a total of 12-members covered the whole of the metropolitan area in the 42 member house.^[3] The district had four members through to 1915.

Adelaide became a three-member district from the1915 election, and then changed from a multi-member tosingle-member district upon the introduction of thePlaymander from the1938 election.^[4]

For most of the next half-century, the electorate was comfortably safe for theLabor Party. A significant redistribution in 1983 saw theLabortwo-party vote reduced from 66 percent to 47 percent, transforming it into a notional marginalLiberal electorate. However, Labor retained the seat at the1985 election, albeit as the most marginal seat in parliament. LiberalMichael Armitage narrowly took the seat at the1989 election – the first time that they or their predecessors, theLiberal and Country League, had won it in its single-member incarnation. The highest Liberal vote in Adelaide occurred at the landslide1993 election, with the Liberal two-party vote rising to a safe 64.1 percent. However, it once again became a marginal Liberal seat at the1997 election.

After the redistribution ahead of the2002 election made the electorate even more marginal, Armitage tried to transfer to the safer Liberal electorate ofBragg, but lost a preselection battle toVickie Chapman. Labor candidateJane Lomax-Smith regained the seat for Labor at the2002 election as a marginal seat, one of two gains that assisted Labor in forming government. It became a safe Labor seat at the landslide2006 election on a 60.2 percent two-party vote, before the Liberals won Adelaide for the second time at the2010 election on a two-party swing of over 14 percent, turning it from safe Labor to marginal Liberal. Despite a −1.8 percent two-party swing, the Liberals retained Adelaide at the2014 election on a 52.4 percent two-party vote.

The 2016 electoral redistribution added the rest ofCollinswood to the electorate, and moved the electorate's northern boundary from Regency Road to several blocks south of Regency Road, removing a significant amount of northernProspect. This increased the Liberal margin from 2.4 percent to an estimated 3.0 percent. The draft of the 2016 Redistribution Report had proposed moving the Liberal-voting suburbs ofWalkerville andGilberton to a neighbouring electorate, but Liberal incumbentRachel Sanderson proceeded with aconcerted campaign, organising the mass letter-box distribution of apro forma document in the two suburbs, which aimed for residents to use the pro forma document to submit their objection to the commission. Of a record 130 total submissions received in response to the overall draft redistribution, over three-quarters (about 100) were from the two letter-boxed suburbs, Walkerville and Gilberton, which resulted in the proposal not appearing in the final redistribution.^{[5][6][7][8][9][10][11]}

Although Sanderson suffered a further 2.0 percent two-party swing, she narrowly retained Adelaide at the2018 election with a 51.0 percent two-party vote. With the Liberals winning government after 16 years in opposition, Adelaide became the government'ssecond most marginal seat, behind onlyKing. TheGreens achieved their highest vote in an electorate at the 2018 election in Adelaide.^[12]

Sanderson was defeated at the2022 South Australian state election by Labor’sLucy Hood.^[13]
