Henri Caesar, also known as Black Caesar, (fl. 1791–1830) was a legendary 19th-century Haitian revolutionary and pirate. Efforts to find historical evidence of his existence have been unsuccessful. According to works of fiction, he was a participant in the Haitian Revolution under Dutty Boukman and Toussaint Louverture as well as active in piracy for nearly a 30-year period during the early 19th century.
