Hawaii is an island state of the United States, in the Pacific Ocean about 2,000 miles (3,200 km) southwest of the U.S. mainland. One of the two non-contiguous U.S. states, it is the only state not on the North American mainland, the only state that is an archipelago, the only state in the tropics, and one of the two U.S. states, along with Texas, that were internationally recognized sovereign countries before becoming U.S. states.
