Ras Dashen (alternatively Ras Dashan or Ras Dejen Ge'ez ራስ ዳሸን rās dāshen or ራስ ደጀን rās dejen, Amh. "head guard") is the highest mountain in Ethiopia and tenth highest mountain of Africa. Part of Simien Mountains National Park, it reaches an elevation of 4,550 metres (14,928 ft). The more common form, "Ras Dashen" is a corruption of its Amharic name, "Ras Dejen", used by the system of the Ethiopian Mapping Authority (EMA) which means "the general who fights in front of the Emperor".
