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.
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).
Grande-Terre's indented coastline is surrounded by coral reefs and the island itself is a limestone plateau. Its surface is a series of rolling hills, white sand beaches and cliffs. The island's beaches consist of both white and black sands, as well as beaches of golden sand. Of the two islands, Grande-Terre is home to the majority of Guadeloupe's farmlands and tourist resorts.
The island has a land area of 586.68 km². At the 2006 census the population of Grande-Terre was 197,603 inhabitants living in 10 communes (municipalities). The population density was 337 inhabitants per km² (872 inh. per sq. miles). The most populated communes are, in descending order of population, Les Abymes (part of the Pointe-à-Pitre urban area), Le Gosier (part of the Pointe-à-Pitre urban area), Pointe-à-Pitre (part of the Pointe-à-Pitre urban area), Le Moule, Sainte-Anne, and Morne-à-l'Eau.
