The Virgin Islands are the western island group of the Leeward Islands, which are the northern part of the Lesser Antilles, and form the border between the Caribbean Sea and the Atlantic Ocean. The archipelago is separated from the Renaissance Islands by the Anegada Passage and from the main island of Puerto Rico by the Virgin Passage.
Christopher Columbus named the islands after Saint Ursula and the 11,000 Virgins, shortened to the Virgins. The official name of the British territory is the Virgin Islands, and the official name of the U.S. territory is the Virgin Islands of the United States. In practice, the two island groups are almost universally referred to as the British Virgin Islands and the U.S. Virgin Islands.
