The Island of Hawaiʻi, also called the Big Island or Hawaiʻi Island is the eastern-most and southern-most in the Hawaiian islands chain in the North Pacific Ocean. With an area of 4,028 square miles (10,432 km²), it is larger than all of the other Hawaiian Islands combined and is the largest island in the United States. The county seat is Hilo.

Hawaiʻi is said to have been named for Hawaiʻiloa, the legendary Polynesian navigator who first discovered it. Other accounts attribute the name to the legendary realm of Hawaiki, a place from which the Polynesians originated (see also Manua), the place where they go in the afterlife, the realm of the gods and goddess.

Captain James Cook, who called them the "Sandwich Islands", was killed on the Big Island at Kealakekua Bay.
