The Abyei Liberation Front was a guerrilla organization in Sudan, active in the Abyei region in the early 1980s and 2000s. It was first formed as an self protection force for the Ngok Dinka tribe in response to attacks on their community by Misseriya Arab but later incorporated to the Sudanese Peoples Liberation Army (SPLA). The group later emerged in 2008 as an Misseriya Arab militia led by Muhammad Omar al Ansari but was disbanded in 2010.
