What is the name of the only U.S. state composed entirely of islands?

Hawaii is the only U.S. state composed entirely of islands. It is an archipelago situated in the Pacific Ocean, consisting of 137 islands, but the major ones include the eight main islands: Hawai'i (the Big Island), Maui, O'ahu, Kaua'i, Molokai, Lāna'i, Ni'ihau, and Kaho'olawe. The state is known for its unique geography, rich culture, and vibrant ecosystems, owing much to its volcanic origins.

Florida, while known for its extensive coastline and numerous islands, is primarily part of the mainland United States and is not solely made up of islands. Alaska, the largest state, also has many islands, particularly in its coastal regions, but it includes a vast land area that is not island-based. New Jersey, located on the mainland, features the New Jersey Shore with some coastal islands, but it is not an island state either. Therefore, Hawaii stands out as the only state that is entirely constituted of islands.
