Which Caribbean archipelago includes Saint Croix, Saint John, and Saint Thomas?

The Caribbean archipelago that includes Saint Croix, Saint John, and Saint Thomas is the Virgin Islands.

These islands lie at the eastern edge of the Greater Antilles, between Puerto Rico and the northern Lesser Antilles. The group is politically divided between the United States Virgin Islands and the British Virgin Islands. Saint Croix, Saint Thomas, and Saint John are the three principal U.S. islands.

A common mix-up is answering “United States Virgin Islands.” That is also the correct political subdivision for those three islands, but the question asks for the wider archipelago, whose standard geographic name is the Virgin Islands. Saint Thomas is home to Charlotte Amalie, the territorial capital, while about 60% of Saint John is protected within Virgin Islands National Park.
