Abyei status referendum
The Abyei status referendum is a delayed referendum that was originally due to be held in 2011 in which the residents of Abyei would decide either to remain part of the Sudanese South Kordofan region or to become part of the Bahr el Ghazal region of South Sudan.
Although an unofficial referendum was held in 2013, as of March 2025 no official referendum has been held.
