Grande-Terre Island (French: île de Grande-Terre or île de la Grande-Terre) is the name of the eastern-half of Guadeloupe proper, in the Lesser Antilles. It is separated from the other half of Guadeloupe island, Basse-Terre, by a narrow sea channel called Rivière Salée (in English Salt River). Pointe de la Grande Vigie, in Grande-Terre, is the northernmost point of Guadeloupe island.
