The Hamar (also spelled Hamer) are an Omotic community inhabiting southwestern Ethiopia. They live in Hamer 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 seven tribal members have ever completed secondary education.
The 2007 national census reported 46,532 people in this ethnic group, of whom 957 were urban inhabitants. The vast majority (99.13%) live in the SNNPR.
According to the Ethiopian national census of 1994, there were 42,838 Hamer language speakers, and 42,448 self-identified Hamer people, representing approximately 0.1% of the total Ethiopian population.
