The following is a list of islands of Arizona. With 113,634.57 square miles (294,312.2 km2) of land, the state of Arizona is the sixth-largest in the United States. It is the third-largest state to not have an ocean coastline—after Montana and New Mexico. Despite being landlocked, Arizona does contain islands, even though the state has the third-lowest amount of water at only 363.73 square miles (942.1 km2) after West Virginia and New Mexico. Arizona's 0.32% of water is the second-lowest percentage after New Mexico's 0.2% of water. The majority of Arizona's islands are in the Colorado River (mainly Lake Mead). Lake Roosevelt also contains a number of islands.
