Hawaii is the only U.S. state located outside North America, the only island state, and the only state in the tropics.
The state encompasses nearly the entire Hawaiian archipelago, which consists of 137 volcanic islands spanning 1,500 miles, which are physiographically and ethnologically part of the Polynesian subregion of Oceania. The eight main islands, from northwest to southeast, are Niʻihau, Kauaʻi, Oʻahu, Molokaʻi, Lānaʻi, Kahoʻolawe, Maui, and Hawaiʻi, after which the state is named.
