Hawaiʻi  is the largest island in the United States, located in the state of Hawaii. It is the southeasternmost of the Hawaiian Islands, a chain of volcanic islands in the North Pacific Ocean. With an area of 4,028 square miles (10,430 km2), it has 63% of the Hawaiian archipelago's combined landmass. However, it has only 13% of Hawaiʻi's population. The island of Hawaiʻi is the third largest island in Polynesia, behind the two main islands of New Zealand

The island is often referred to as the Island of Hawaiʻi, the Big Island, or Hawaiʻi Island to distinguish it from the state. Administratively, the whole island is coextensive with Hawaiʻi County.
