The Hamer (also spelled Hamar) are a tribal people in southwestern Ethiopia. They live in Hamer Bena woreda (or district), a fertile part of the Omo River valley, in the Debub Omo Zone of the Southern Nations, Nationalities, and Peoples Region (SNNPR).

They are largely pastoralists, so their culture places a high value on cattle.The Assistant Administrator of Hamer Bena, Ato Imnet Gashab, has commented that only six tribal members have ever completed secondary education.
