Cap-Haïtien (Okap or Kapayisyen in Kréyòl) is a city of about 190,000 people on the north coast of Haiti. Previously, named as Cap-Français and Cap-Henri, it was an important city during the colonial period and was the first capital of the Kingdom of Northern Haiti under King Henri Christophe.

Cap-Haïtien's distance from Haïti's capital, Port-au-Prince, combined with the dire condition of Haïti's transportation infrastructure, has often made Cap-Haïtien an incubator for revolutionary or Anti-Government figures. On February 5-29, 2004, the city was taken over by militants who opposed to the rule of Haïtian president Jean-Bertrand Aristide, forcing him out from the country.
