text: Actually I think that "countries" is more accurate.\n\nEver since the separation of Eritrea from Ethiopia, one should include both Eritrea and Ethiopia as part of the horn as a minimum. \n\nHowever, the horn of Africa is commonly referred to as a region in Africa. The region includes Eritrea, Ethiopia, Somalia, and of course the tiny country of Djibouti.\n\nThe common claim that only Ethiopia is the horn of Africa is quite odd because the horn extends out into into the Arabian Sea and Ethiopia is a landlocked country. Ethiopia does not include any of the coastal land of the Horn of Africa.
