2018 South Sumatra gubernatorial election

The 2018 South Sumatra gubernatorial election took place on 27 June 2018 as part of the simultaneous local elections. It was held to elect the governor of South Sumatra along with their deputy, whilst members of the provincial council (Dewan Perwakilan Rakyat Daerah) will be re-elected in 2019.

Incumbent governor Alex Noerdin was barred from participating due to constitutional term limits. Four pairs of candidates contested the election, including incumbent vice governor Ishak Mekki. Other candidates are regents of regencies within the province: Herman Deru from East Ogan Komering Ulu, Aswari Rivai from Lahat and Dodi Reza Alex Noerdin from Musi Banyuasin.

Herman Deru would proceed to win the election, winning around 36 percent of the votes, ahead of Noerdin who placed second with 31 percent.

The candidates were assigned their ballot numbers on 13 February 2018.
