Grande-Terre Island (French: île de Grande-Terre / île de la Grande-Terre [ɡʁɑ̃d tɛʁ]; Antillean Creole: Gwanntè or Granntè) 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. To the east lies La Désirade, and to the south lies Marie Galante.
Despite its name, Grande-Terre (literally "Large Land" in French) is smaller than Basse-Terre Island. It was called like that, in contrast with the much smaller Petite Terre Islands ("Small Land" Islands), two very small islands located about 10 km south-east of the Grande-Terre (see map to the left).
