Lynn Arnold Labor Dean Brown Liberal State elections were held in South Australia on 11 December 1993.

Labor premier John Bannon had resigned over the issue in 1992, being replaced by Lynn Arnold just over a year before the election.

A warning sign of things to come came with the March 1993 federal election, which saw two of Labor's longest-held seats in South Australia, Hindmarsh and Grey, fall to the Liberals.

Adelaide, which had been Labor's power base in the state for decades, swung over dramatically to support the Liberals.

In turn, the Liberals were reduced to a minority government as a result of the 1997 election, following another record two-party swing in the other direction of 9.5 percent.
