eastern suburb of Port-au-Prince, southern Haiti, on the cool northern hills of the Massif de la Selle. Named for Alexandre Sabès Pétion (Pétion, Alexandre Sabès), who fought in Haiti's wars for independence in the early 19th century and was later president of the southern kingdom of Haiti, it is primarily a residential and resort area. It is linked to Port-au-Prince, the national capital, by three main routes, including a winding toll road, the proceeds of which were intended to finance Duvalierville, a model city, now defunct. Pop. (1997 est.) 76,155.
