Lānaʻi (/ləˈnaɪ/; Hawaiian: [laːˈnɐʔi] or [naːˈnɐʔi]) is the sixth-largest of the Hawaiian Islands and the smallest publicly accessible inhabited island in the chain. It is also known as Pineapple Island because of its past as an island-wide pineapple plantation. The island's only settlement of note is the small town of Lānaʻi City. As of 2012, the island was 98% owned by Larry Ellison (Founder and Chairman of Oracle), with the remaining 2% owned by the state of Hawaii.
