What is the capital of Haiti?

The capital of Haiti is Port-au-Prince. It is the largest city in the country and serves as the political, economic, and cultural center of Haiti. Located on the Caribbean Sea, Port-au-Prince has a rich history and is known for its vibrant art scene and historical landmarks. This distinction makes it the correct answer, as the other cities listed are capitals of different countries: Havana is the capital of Cuba, Santo Domingo is the capital of the Dominican Republic, and Kingston is the capital of Jamaica. Each of these capitals plays a significant role in their respective nations but does not pertain to Haiti.
