The British Virgin Islands (BVI) are one of three political divisions of the Virgin Islands archipelago located in the Lesser Antilles, between the Caribbean Sea and the North Atlantic Ocean. The BVI are the easternmost part of the island chain. The land area totals 151 km² (about 0.9 times the size of Washington, DC) and comprises 16 inhabited and more than 20 uninhabited islands. The islands of Tortola (21mi²), Anegada (14mi²), Virgin Gorda (8mi²) and Jost van Dyke (4mi²) are the largest. Maritime claims include 12 nmi (22.2 km; 13.8 mi) territorial sea and a 200 nmi (370.4 km; 230.2 mi) exclusive fishing zone. In terms of land use, it is 20% arable land, 6.67% permanent crops and 73.33% other as of a 2005 figure. It has strong ties to nearby U.S. Virgin Islands and Puerto Rico.

The islands' terrain consists of coral islands, and is relatively flat. The volcanic islands are steep and hilly. Its lowest point is the Caribbean Sea and its highest point is Mount Sage at 521 metres (1,709 ft) above sea level. The country contains 80 km of coastline. There is limited natural fresh water resources (except for a few seasonal streams and springs on Tortola, most of the islands' water supply comes from wells and rainwater catchments).
