Anegada is the northernmost of the British Virgin Islands (BVI), a group of islands which form part of the archipelago of the Virgin Islands. It lies approximately north of Virgin Gorda. Anegada is the only inhabited British Virgin Island formed from coral and limestone, rather than being of volcanic origin. While the other islands are mountainous, Anegada is flat and low. Its highest point is only about above sea level, earning it its name which is the Spanish term for the flooded land, "tierra anegada".
At about 15 square miles (38 square kilometers), Anegada is the second largest of the British Virgin Islands, but it is also the most sparsely populated of the main islands, with a population as at the 2010 Census of 285. Most of the population on Anegada live in the only village, The Settlement.
A fictional island called "Virgin Magra" (skinny virgin) described in the Rafael Sabatini novel Captain Blood precisely matches the topography of Anegada.
