Geography of Haiti

Physical characteristics

Haiti's total area is approximately 27,750 km², with about 27,560 km² of land and modest inland water. The country has an extensive coastline—roughly 1,771 km—bordering the Atlantic Ocean to the north and the Caribbean Sea to the south and west. It shares a 360 km land boundary with the Dominican Republic. Offshore and adjacent states include Cuba to the northwest and Jamaica to the southwest; the passages separating these islands include the Windward Passage and the Jamaica Channel.

Mountains, plains and waterways

The interior is predominantly mountainous, with several ranges running across the island. The highest summit is Pic la Selle in the Massif de la Selle, rising to the island's greatest elevations. Major rivers such as the Artibonite flow from the highlands toward lower coastal plains and sustain agricultural valleys. A notable inland water body is Lake Azuei (Étang Saumâtre), a saline lake near the border region.

Peninsulas, islands and bays

Two prominent peninsulas extend into surrounding seas: the Northern (or Northwestern) Peninsula, sometimes called the Saint-Nicolas Peninsula, and the Southern Peninsula, historically known as the Tiburón Peninsula. Between them lies a large embayment, the Gulf of Gonâve, named for Gonâve Island in its center. That gulf was also historically referred to as the Gulf of Léogane in reference to one of Haiti's oldest towns; the historical connection is often noted in local accounts and maps (historical). The gulf and other bays form important natural harbors and fishing grounds (bay).

Climate, soils and environment

Haiti has a tropical climate with regional variation: coastal lowlands are typically hot and humid, while higher elevations are cooler and can be relatively dry. Soils vary from fertile valleys to degraded slopes; deforestation and erosion have been persistent environmental problems, reducing agricultural productivity and increasing vulnerability to storms. Conservation and reforestation are recurring subjects in national planning and international aid efforts.

Geology, hazards and human geography

Geologically, Hispaniola lies near the boundary between the North American and Caribbean tectonic plates, which makes the island prone to seismic activity and occasional large earthquakes. The 2010 earthquake that struck the Port-au-Prince region underscored this hazard and its social impacts. Urbanization concentrates population and infrastructure along coastal plains and around Port-au-Prince, while rural communities occupy mountain valleys and plateau areas. Islands such as Gonâve play roles in fisheries and local transport, and the network of rivers and coastal bays supports rice terraces, fishing, and small-scale farming.

Notable facts and distinctions

• Haiti is the western part of Hispaniola and shares the island with the Dominican Republic.
• The island has strategic position relative to Cuba and Jamaica, separated by the Windward Passage and the Jamaica Channel.
• Early European contact is associated with Christopher Columbus, who reached portions of Hispaniola in 1492, and subsequent colonial developments shaped the island's human geography.
• Protected areas, watershed management and coastal zone planning remain important for reducing flood, landslide and drought risks.
