The following outline is provided as an overview of and topical guide to the British Virgin Islands: British Virgin Islands (BVI) – British overseas territory located in the eastern portion of the Virgin Islands Archipelago in the Caribbean Sea. The Virgin Islands are part of the Leeward Islands of the Lesser Antilles. The United States Virgin Islands comprises the western portion of the archipelago. Technically the name of the Territory is simply the "Virgin Islands", but in practice since 1917 they have been almost universally referred to as the "British Virgin Islands" to distinguish the islands from the American Territory. To add to the regional confusion, the Puerto Rican islands of Culebra, Vieques and surrounding islands began referring to themselves as the "Spanish Virgin Islands"
