The 2026 South Australian Legislative Council election was held on 21 March 2026 to elect 11 of the 22 members of the South Australian Legislative Council as part of the 2026 South Australian state election.

The election was notable for Pauline Hanson's One Nation party strongest performance in South Australia, winning three Legislative Council seats and four House of Assembly Seats, and the collapsed vote of the South Australian Liberal Party.

In the Legislative Council, One Nation won three seats, one more than the South Australian Liberal Party. Elected were 5 Labor, 3 One Nation , 2 Liberal and 1 SA Greens. Carrying over from the 2022 election were 5 Labor, 4 Liberal, 1 Green and 1 Sarah Game Fair Go, resulting in the total numbers in the Council - 10 Labor, 6 Liberal, 3 One Nation, 2 SA Greens and 1 Sarah Game Fair Go.

SA Best which won 2 seats at the 2018 election failed to win a single seat along with Jing Lee, a former Liberal, who had created a new party Better Community.

Tammy Franks a member of the Legislative Council since 2010 as an SA Green, in September 2024 said she would not contest the next election. In May 2025, she resigned from the South Australian Greens, citing tensions within the party, and reiterated that she still did not intend to contest the next election "at this point". However, in February 2026, she announced that she would run as an independent candidate for the Legislative Council in the election the following month. Franks was unsuccessful in her attempt to be elected as an Independent receiving 0.5% of the vote.

Sarah Game who was the first elected One Nation candidate in South Australia at the 2022 election was not up for re-election as her 8-year term ends in 2030. Game had resigned from One Nation in May 2025 to become an Independent. In July 2025 she founded a new party which, registered as Sarah Game Fair Go for Australians. The party contested the election but 10 days before the election, the party's lead upper house candidate Chris McDermott announced that he would defect to become an independent if he was elected. Game urged voters to not back her own party in the upper house and the party didn't win any seats in the election receiving just 0.24% of the vote.
