Abstract: The main objective of this article is to investigate Maaga indigenous conflict resolution institution among the Libido-Mareko ethnic group in Gurage Zone Southern Ethiopia. To attain this objective, the article employed both secondary and primary data sources. Both primary and secondary data were organized thematically and analyzed through systematic interpretation and triangulation of various sources. The article found that conflicts are manifested at family, neighborhood and clan level with varying magnitude. The indigenous conflict resolution institution among Libido-Marko ethnic group has two stages of conflict resolution involving the Maaga and Raaga. The two stages of conflict resolution are highly interconnected and refer cases from one setting to another. The first stage, Maaga, has five structures: Minan woran jaana (family congregation), Hegeegan janna, (intra- and inter-village structure), nihuss-gossa (sub-clan), gichchotan hafa (clan structure) and Meexe hafa/libidan dummichcha (Libido-Mareko assembly).
