2006 South Australian local elections

The 2006 South Australian local elections were held in November 2006 to elect the councils of 66 of the 68 local government areas (LGAs) in South Australia. Many councils also held mayoral elections.

As per usual, no election was held in Roxby Council as it is served by an administrator who performs all the functions of a council. The election in Adelaide was delayed until November 2007 to enable a review of its representation system.

At the close of nominations on 19 September, a total of 1,094 candidates had nominated for mayoral or councillor positions. 56 elections were uncontested.

Two elections were declared 'failed', each because of the withdrawal of a candidate for medical reasons − Kensington Ward in Norwood Payneham & St Peters and Eastwood & Glenunga Ward in Burnside.

The Australia First Party had their first local elections victory, with Bruce Preece elected in Prospect. However, he resigned from the party five days after being elected.

Aftermath
Following the elections, 37% of voters stated that political advertising received from 230 candidates influenced how they voted.
