Privately Owned Islands in Hawaii: Necker, Lanai, Niihau

Yes, several Hawaiian islands are privately owned.

Notable Examples

• Lanai (141 sq mi): 98% owned by Larry Ellison (Oracle co-founder) since 2012. Two luxury resorts (Four Seasons), ~3,000 residents. Formerly Dole pineapple plantation.
• Niihau (70 sq mi): Owned by the Robinson family since 1864. "Forbidden Isle"—access restricted to owners, guests, Native Hawaiian residents (~170), and military. No tourism, no cars, no internet. Preserves traditional lifestyle.
• Necker Island (Mokumanamana, 46 acres): Owned by Larry Ellison (purchased 2012). Uninhabited, rocky, NW of Kauai. Part of Papahānaumokuākea Marine National Monument. Archaeological sites (heiau).
• Kahoolawe (45 sq mi): State-owned (not private); former Navy bombing range; now cultural reserve.

Legal Context

• Private ownership dates to Great Mahele (1848)—Hawaiian land privatization.
• Owners have fee simple title but are subject to state/county zoning, coastal zone management, and Native Hawaiian gathering/access rights.
• Niihau's unique status involves a state deed restriction limiting development.

Most Hawaiian islands are state or federal public land. Private islands are exceptional—and tightly regulated.
