The 2024 Sierra prefectural election was held on Saturday 11 May 2024 to elect the 35 members of the Sierra Prefectural Assembly. The gubernatorial election was held on the same date.
The incumbent Social Democratic government, led by Premier Jim Stephenson, was seeking a fourth term in office, but was defeated by the opposition Liberal Party of Sierra, led by Opposition Leader Kylie Langford. The Sierra National Party, Sierra Party, other minor parties and independents also contested the election.
This was the first prefectural election in Sierra contested under the new mixed-member proportional system which was approved by voters in a 2023 referendum. The number of electorates remained at 25, and 10 list seats were created for proportional levelling, for a total of 35 seats in the new parliament with 18 seats required for a majority.
The Liberal Party won 10 seats, and was able to form government by forming a coalition with the National Party, which won 5 seats, and obtaining the confidence and supply of the Sierra Party, which won 4 seats.
