Elidar (also spelled Eli Da'ar) is a woreda in Afar Region, Ethiopia.
Part of the Administrative Zone 1, Elidar is bordered on the south by the Awash River which separates it from Asayita, on the west by Dubti, on the northwest by Kori, on the north by the Administrative Zone 2, on the northeast by Eritrea, and on the east by Djibouti.
In early 1976, Derg soldiers led by Habib Mohamed Yayyo clashed with Afar fighters at Do'oroita near Elidar, with casualties on both sides.
From documents captured by the soldiers, they learned that this group, who shortly afterwards organized themselves as the Afar National Liberation Movement, was leftist in political orientation and unaffiliated with the Afar Liberation Front of Sultan Alimirah Hanfadhe, and subsequently brokered a peace treaty with them which led the Derg to include a clause in their Program for the National Democratic Revolution which recognized the rights of the nationalities of Ethiopia.
