Islands & Counties
There are eight main islands in the State of Hawai’i. The State includes the main islands and the Northwest Hawaiian Islands.
The island of Hawai’i, which is Hawai’i County, is informally called the Big Island to avoid confusion with the state name of Hawai’i. Both Maui County and Kaua’i County include more than one island within their political borders. The island of O’ahu isn’t O’ahu County, but is called Honolulu County. The Kalaupapa Peninsula which was a leper colony is administered jointly by the National Park Service and the Hawai’i Department of Health and is a separate political unit called Kalawao County.
