State elections were held in South Australia on 15 September 1979. All 47 seats in the South Australian House of Assembly were up for election. The incumbent Australian Labor Party led by Premier of South Australia Des Corcoran was defeated by the Liberal Party of Australia led by Leader of the Opposition David Tonkin.
A Norwood by-election was held due to the seat's election result being overturned by a court decision, which saw the seat lost from the Liberals to Labor, which meant the Liberals held 24 seats with Labor on 20 seats.

Background
Premier Don Dunstan abruptly resigned on 15 February 1979 due to ill health, and was succeeded by Deputy Premier Des Corcoran.
Spurred by positive opinion polls and seeking to escape the shadow of Dunstan, Corcoran called a snap election (without pre-informing the party apparatus) in order to gain a mandate of his own. The election campaign was plagued by problems, which allowed an opening for the Liberals under Tonkin. It didn't help matters that The Advertiser was biased toward the Liberal campaign.
Labor suffered a large swing, losing eight seats to the Liberals. The Liberals also won 55 percent of the two-party vote to Labor's 45 percent. In most of Australia, this would have been enough for a landslide Liberal victory. However, most of the Liberal margin was wasted on massive landslides in rural areas. The Liberals only won 13 seats in Adelaide, netting them a total of 26 seats, a bare majority of two. Narrow as it was, it was the first time the main non-Labor party in South Australia had won the most seats while also winning a majority of the vote since the Liberal and Country League won 50.3 percent of the two-party vote in 1959.
Corcoran was bitter in defeat, believing sections of the ALP had undermined him during the campaign. He resigned as leader soon after the election, and retired from politics in 1982.
In the South Australian Legislative Council, the sole balance of power was held unbroken by the Australian Democrats from their inception in mid-1970s, until the late 1990s. Though the Democrats would exceed 16 percent of the vote at the 1997 election, during the following term the Democrats would lose the sole balance of power for the first time, sharing the balance of power with independent members, slowly losing numbers and influence, until they were eventually without parliamentary representation as of the 2010 election.
Post-election pendulum
One of the seats lost to the Liberals had been Dunstan's old seat of Norwood. However, in 1980, a court overturned Liberal Frank Webster's victory, triggering a 1980 Norwood by-election. Greg Crafter regained the seat for Labor, reducing the Liberal government to 24 seats, a one-seat majority. A 1982 Mitcham by-election and 1982 Florey by-election were triggered, the Democrats retained Mitcham by 45 votes, Labor increased their margin in Florey.

For this election, the electoral system used for the Legislative Council was a party-list proportional representation system, with elements of the single transferable vote. Voters voted preferentially for party lists. All parties below the threshold of 50% of the Droop quota had their votes transferred to the next preference on the ballot paper for a party above the threshold. Seats were then distributed to parties using the largest remainder method with the Droop quota.
The two Liberal Movement members elected in 1975 had rejoined the Liberal Party.
In 1982, Labor MLC Norm Foster resigned from the Labor Party (to vote in favour of the Olympic Dam development) and sat the remainder of his term (until the 1982 election) as an independent.
