State elections were held in South Australia on 9 February 2002. All 47 seats in the South Australian House of Assembly were up for election, along with half of the 22 seats in the South Australian Legislative Council. The incumbent Liberal Party of Australia led by Premier of South Australia Rob Kerin was defeated by the Australian Labor Party led by Leader of the Opposition Mike Rann. The Labor Party won 23 out of 47 seats, and then secured the one more seat it needed for a majority by gaining the support of independent Peter Lewis.
This was the first election since Labor narrowly lost as opposition in the 1997 election, doing much better than most analysts predicted, forcing the Liberals to minority government after their comprehensive loss in the 1993 election where Labor were reduced to just ten seats. Coming into the 2002 election, the Liberal Government had faced a number of scandals including the Motorola affair, over which Premier John Olsen was forced to resign in October 2001. He was succeeded by Rob Kerin, who had less than three months to govern before the election was called.

Labor won two seats from the Liberals, the districts of Adelaide (Jane Lomax-Smith) and Colton (Paul Caica). This gave Labor 23 seats, Liberals 20 seats, SA Nationals one seat, and three seats to independents. To form majority government, a party needed 24 seats out of 47. Most analysts expected Kerin to form a minority government with the support of Nationals MP Karlene Maywald, and the three independents, who were all former Liberal party members.
On 13 February, one of those crossbenchers, former Liberal Peter Lewis, announced that he had signed an agreement with Labor leader Mike Rann to support a Labor Government in exchange for holding a constitutional convention, making him speaker of the House of Assembly, and concessions for his electorate including the phasing out of commercial fishing in the River Murray, prioritising the eradication of the branched broomrape weed, changing water rates for irrigation, fast-tracking a feasibility study for a weir and lock at Wellington, and improving rural roads. This agreement effectively made Rann premier-elect by one seat.
However, following parliamentary precedent established by Don Dunstan following the 1968 election, Kerin refused to resign until Rann and Labor demonstrated that they had majority support on the floor of the House of Assembly. Kerin claimed to be within this rights to take this course, as longstanding precedent in the Westminster system holds that the incumbent premier should have the first opportunity to form a government if no party has a majority.
After three weeks of stalemate, the House of Assembly was called into session several weeks earlier than usual. With Lewis in the speaker's chair, the Kerin Government was defeated on the floor of the House of Assembly on 5 March 2002, after Kerin moved a confidence motion in his own government and lost. Rann then advised Governor Marjorie Jackson-Nelson that he could form a government, which was duly sworn in the following day.
Rann later shored up his government's majority by reaching agreements with crossbenchers Maywald and McEwen, giving them cabinet posts in exchange for their support of the government.
