Horn of Africa Map

Where Is the Horn of Africa?

The Horn of Africa is the peninsula on the far eastern tip of Africa that juts into the Arabian Sea, with the Gulf of Aden to the north and the Indian Ocean to the east. It is made up of four countries: Ethiopia, Somalia, Eritrea and Djibouti. Together they cover about 1.9 million km² and are home to roughly 155 million people, most of them in Ethiopia. Across the narrow Bab-el-Mandeb strait lies Yemen on the Arabian Peninsula.

On a map, look for the "horn" shape pointing east between roughly 0° and 18° N. Ethiopia fills the highland interior and has been landlocked since Eritrea became independent in 1993; Eritrea and Djibouti hold the Red Sea coast; Somalia wraps around the tip, including Cape Guardafui (Ras Asir), the easternmost point of mainland Africa. The self-declared Republic of Somaliland in the north-west of Somalia runs its own affairs but is not internationally recognised as a state. Some broader definitions of the "Greater Horn" also include Kenya, Sudan, South Sudan and Uganda. The Horn is usually treated as part of East Africa – see also our East Africa map.

The Four Countries of the Horn of Africa

The Horn of Africa encompasses four sovereign nations, each with distinct histories, cultures, and geographical features, yet united by their shared location on this strategic peninsula.
