Moumouni Adamou Djermakoye (May 22, 1939 – June 14, 2009) was a Nigerien politician and the President of the Nigerien Alliance for Democracy and Progress (ANDP-Zaman Lahiya). He was an important minister during the regime of Seyni Kountché and subsequently served as Niger's Ambassador to the United States from 1988 to 1991; later, after founding the ANDP, he served as President of the National Assembly of Niger from 1993 to 1994. He was the ANDP's candidate in four presidential elections, beginning in 1993; he was also a deputy in the National Assembly from 1999 to 2009 and the President of the High Court of Justice from 2005 to 2009.
His family names, Moumouni Djermakoye, marked him as a descendant—but not heir—of the most powerful ruling dynasty of Djerma society, that of the Djermakoy of Dosso: the first amongst equals of Djerma rulers and a house especially favoured during the colonial period.
Djermakoye entered the military as a young officer, and took part in Seyni Kountché's April 1974 coup which overthrew President Hamani Diori. He became a key member of the ruling council, and developed a personal power base in Dosso.
Following the 1974 coup, Djermakoye served as Minister of Foreign Affairs and Cooperation from April 22, 1974 to September 10, 1979. On the latter date, he was named Minister of Youth, Sports, and Culture, in which position he served until he was named Minister of Public Health and Social Affairs on August 31, 1981. He remained in the latter position until January 24, 1983. In May 1988 he was named Ambassador to the United States and Permanent Representative to the United Nations. He presented his credentials as Ambassador to the United States on September 19, 1988, serving in that post until mid-1991.
In 1991, Djermakoye was defeated by Tandja Mamadou in a bid to become leader of the National Movement for the Development of Society (MNSD). This struggle was marked by a question of ethnicity: Djermakoye, who was a member of the dominant ethnic group in the party (the Djerma), lost to Tandja, who was not. After his defeat, he formed a group called the Club of Moumouni Adamou Djermokoye's Friends (CAMAD), which later became the ANDP.
