The 1993 South Australian state election was held on 11 December 1993.

Hartley Labor MHA Terry Groom resigned from the party in 1991 after losing preselection to contest the seat of Napier at the 1993 election. Elizabeth Independent MHA Martyn Evans was admitted to the Labor Party and endorsed as a candidate in late 1993.

A redistribution was completed in 1991, incorporating changes to the Constitution instituted by referendum requiring the electoral map to be drawn with an eye to ensuring the seat result reflected the statewide vote. The Labor seats of Albert Park, Baudin, Briggs, Gilles, Henley Beach, Stuart, Todd, Walsh and Whyalla; the Liberal seats of Alexandra, Hayward, Mount Gambier, Mitcham, Murray-Mallee and Victoria; and the Independent-held seat of Semaphore were abolished. The redistribution created the notionally Labor seats of Elder, Giles, Hart, Kaurna, Lee, Reynell, Taylor, Torrens and Wright; and the notionally Liberal seats of Colton, Finniss, Frome, Gordon, MacKillop, Ridley and Waite. The Labor seat of Hartley became notionally Liberal, while the Liberal seats of Hanson and Newland became notionally Labor.
