Massillon Coicou (Haitian Creole: Masiyon Kwakou, 9 October 1867 – 15 March 1908[1]) was a Haitian poet, novelist, playwright, and politician. Born in Port-au-Prince, Coicou was educated in a Catholic school for boys. He was appointed as the Haitian Chargé d'Affaires Étrangères for the Haitian Republic[2] in France, where several of his works were published. Opposed to the presidency of Pierre Nord Alexis, Coicou publicly announced his intentions to overthrow Nord Alexis' government. He and his two brothers were subsequently executed by the President's orders on the night of 14–15 March 1908.[3]
