Henri Namphy (born November 2, 1932 in Cap-Haïtien, Haiti) was a Haitian general and political figure who served as President of Haiti's interim ruling body, the National Council of Government, from February 7, 1986 to February 7, 1988. He served again as President of Haiti from June 20, 1988 until his deposition on September 17, 1988 in the September 1988 Haitian coup d'état.
Following the fall of the government headed by President-for-Life Jean-Claude Duvalier, who fled the country with his family in 1986, Lieutenant General Namphy became president of the interim governing council, made up of six civilian and military members, which promised elections and democratic reforms. His regime was given the moniker “duvalierism without Duvalier”.
Namphy, who enjoyed a reputation for being honest and apolitical, had trouble in his early weeks in power; Haitians ceased their celebrations over the departure of Duvalier and started rioting and looting. In March 1986, as violence swept the capital, Port-au-Prince, the popular justice minister resigned from the ruling council and Namphy dismissed three other members who had close ties with the Duvalier regime. The new council had two other members apart from Namphy. The council had difficulty in exerting its authority because of frequent strikes and demonstrations.
An election held in October for a constituent assembly to prepare a draft constitution reflected a lack of public interest in determining the country's political future. The first attempt at elections, in November 1987, ended when some three dozen voters were massacred. In January 1988 Leslie Manigat won an election that was widely considered fraudulent, and Namphy overthrew him on June 20 in the June 1988 Haitian coup d'état after Manigat had dismissed Namphy as army commander. Namphy remained in power until September 17, 1988, when he was deposed by a group of young officers organized by General Prosper Avril.
