Dantès Bellegarde (18 May 1877 – 16 June 1966)  was a Haitian historian and diplomat. He is best known for his works Histoire du Peuple Haïtien (1953), La Résistance Haïtienne (1937), Haïti et ses Problèmes (1943), and Pour une Haïti Heureuse (1928-1929).
Bellegarde was born in Port-au-Prince to a poor mulatto family. His impoverished but small bourgeoisie background descended from several historical figures in Haiti's history. His maternal great-grandfather Jacques Ignace-Fresnal was an officer in the army and Haiti's first Minister of Justice, and founder of Haitian Freemasonry. His paternal grandfather, General Jean-Louis Bellegarde, was a former Governor of Port-au-Prince.
