The Derg or Dergue (Amharic: ደርግ, lit.'committee' or 'council'), officially the Provisional Military Administrative Council (PMAC), was the military junta that ruled Ethiopia, including present-day Eritrea, from 1974 to 1987, when they formally "civilianized" the administration although remained in power until 1991.

The Derg was established on 21 June 1974 as the Coordinating Committee of the Armed Forces, Police and Territorial Army, by junior and mid level officers of the Imperial Ethiopian Army and members of the police. The officers decided everything collectively at first, and selected Mengistu Haile Mariam to chair the proceedings. On 12 September 1974, the Derg overthrew the government of the Ethiopian Empire and Emperor Haile Selassie during nationwide mass protests, and three days later formally renamed itself the Provisional Military Administrative Council. In March 1975 the Derg abolished the monarchy and established Ethiopia as a socialist state under a military-led provisional government. The abolition of feudalism, increased literacy, nationalization, and sweeping land reform including the resettlement and villagization from the Ethiopian Highlands became priorities. Mengistu became chairman in 1977, launching the Red Terror (Qey Shibir) political repression campaign to eliminate political opponents, with tens of thousands imprisoned and executed without trial.

By the mid-1980s, Ethiopia was plagued by multiple issues, such as droughts, economic decline and increasing reliance on foreign aid, recovering from the Ogaden War, and the 1983–1985 famine from which the Derg itself estimated more than a million deaths during its time in power. Conflicts between the Derg and various ethnic militias saw a gradual resurgence, particularly the Ethiopian Civil War and the Eritrean War of Independence. Mengistu formally abolished the Derg in 1987 and formed a Marxist-Leninist one party state, the People's Democratic Republic of Ethiopia led by the Workers' Party of Ethiopia, with a new government containing civilians but still dominated by members of the Derg.

In May 1991, the Derg regime fell to the Ethiopian People's Revolutionary Democratic Front, ending the civil war that had been ongoing since 1974 following the toppling of the Ethiopian Empire.
