The single largest landowner in Hawaii is the State of Hawaii itself, which holds between 1.3 and 1.5 million acres of public trust land across the islands. Among private owners, Kamehameha Schools sits at the top with roughly 363,800 acres, far ahead of any individual or company.1Kamehameha Schools. History – Investment Management After those two, the list of who owns the most land in Hawaii runs through a short bench of ranches, trusts, billionaires, and one family that has held an entire island since 1864.
The concentration is extreme by mainland standards. By the mid-1960s, the Hawaii Legislature found that state and federal governments owned about 49 percent of all land, and another 47 percent belonged to just 72 private landowners.2State of Hawaii Office of the Auditor. Study of the Resale of Leasehold Properties Converted to Fee Simple Under the Hawaii Land Reform Act of 1967 The ranking below reflects what that pattern looks like today.
The State of Hawaii
When Hawaii became a state in 1959, the federal Admission Act transferred most former crown and government lands to the new state government as a public trust.3Department of the Interior. An Act to Provide for the Admission of the State of Hawai’i into the Union Those ceded lands alone total an estimated 1.2 to 1.4 million acres, though an exact inventory has never been completed because some parcels were double-counted or lumped in with non-ceded lands over the years.4Legislative Reference Bureau. Ceded Lands The Department of Land and Natural Resources manages the bulk of it, including forest reserves, coastal zones, and watersheds.
A separate state agency, the Department of Hawaiian Home Lands, manages about 200,000 acres set aside for homesteading by native Hawaiians. Congress created the program in 1921 through the Hawaiian Homes Commission Act, which designated those parcels as “available lands” for residential, agricultural, and pastoral use by people of at least 50 percent Hawaiian ancestry.5U.S. Department of the Interior. Hawaiian Home Lands Trust Waitlists for homestead leases have stretched for decades.
The Federal Government
Federal holdings in Hawaii amount to roughly 830,000 acres on paper, according to the Congressional Research Service, though about 253,000 of those are submerged lands and waters within the Hawaiian Islands National Wildlife Refuge.6Congress.gov. Federal Land Ownership: Overview and Data The actual dry-land federal footprint is closer to 575,000 acres. The National Park Service and the Fish and Wildlife Service hold the largest shares, followed by Department of Defense installations that include major Army training areas and naval facilities across Oahu and the Big Island. Between state and federal lands, government entities control close to half of Hawaii’s total land area.
Kamehameha Schools
Kamehameha Schools, historically known as the Bishop Estate, owns more than 363,800 acres across the islands, which makes it the largest private landowner in Hawaii by a wide margin.1Kamehameha Schools. History – Investment Management The trust traces back to Princess Bernice Pauahi Bishop, who signed her last will on October 31, 1883, directing that the remainder of her estate be used to establish and maintain schools for Hawaiian children.7Kamehameha Schools. Kukahekahe: Pauahi’s Will and the Boys School Pauahi was a direct descendant of Kamehameha I and one of the last members of the royal Kamehameha line, so her estate carried in massive tracts inherited through ali’i land awards from the Great Mahele of 1848.
The holdings range from commercial properties in downtown Honolulu to conservation forests on the Big Island and Maui. Revenue from leasing and developing this land funds a statewide school system, community education programs, and scholarships.
Larry Ellison
Oracle co-founder Larry Ellison purchased approximately 98 percent of the island of Lanai in 2012, acquiring roughly 87,000 of the island’s 90,000 total acres in a single transaction. Ellison has since invested heavily in sustainable agriculture projects, luxury hospitality, and renewable energy infrastructure on Lanai, effectively controlling its economic direction.
Parker Ranch
Parker Ranch on Hawaii Island operates on over 135,000 acres, making it one of the largest cattle ranches in the country.8Parker Ranch. Our Story Founded in the early 1800s, it now operates under a charitable trust focused on environmental stewardship, community development, and investment in healthcare and education for the Waimea area.
The Robinson Family
The Robinson family has privately owned the entire island of Niihau since 1864, when their ancestor Eliza Sinclair purchased it from the Hawaiian monarchy. At about 44,800 acres, Niihau is known as the “Forbidden Island” because the family restricts outside access to preserve the traditional Hawaiian-speaking community that lives there.9Department of Land and Natural Resources. Ni’ihau The Robinsons also hold a separate estate of roughly 55,000 acres on Kauai, bringing their combined holdings close to 100,000 acres.
Other Major Landowners
Several other names round out the list of Hawaii’s largest landholders:
- Molokai Ranch holds roughly 58,000 acres on Molokai.
- Grove Farm owns about 36,000 acres on Kauai.
- Alexander & Baldwin, founded as a sugar plantation agency in 1870, was once among the top five largest private landowners in Hawaii with well over 100,000 acres. The company closed its last sugar operation in 2016 and converted to a real estate investment trust. Its current portfolio centers on approximately four million square feet of commercial retail, industrial, and office space, along with fee interests in 146 acres of ground lease assets.10Alexander & Baldwin.

- Mark Zuckerberg has assembled an estate of more than 2,300 acres on Kauai’s north shore through a series of purchases since 2014. The acquisitions have drawn criticism from some residents who view them as a continuation of outsiders consolidating Hawaiian land.
Why the List Looks This Way
Before Western contact, land in Hawaii was not individually owned. The king held authority over all territory, and commoners farmed parcels within an ahupuaa, a wedge-shaped division running from mountain to sea, under the oversight of chiefs. In 1848, King Kamehameha III initiated the Great Mahele, a sweeping land division that introduced Western-style private property for the first time. Of roughly four million total acres, the king kept about one million as crown lands, designated approximately 1.5 million as government lands, and distributed the remaining 1.5 million to about 245 chiefs.11State of Hawaii DCCA. Land in Hawai’i
Common Hawaiians received the right to claim small parcels they physically occupied and cultivated. These plots, known as kuleana lands, were authorized by the Kuleana Act of 1850, but the claims process was unfamiliar and confusing to most commoners, and relatively few obtained title. The vast majority of land ended up with the monarchy, the government, and a small circle of chiefs. When those estates later passed to missionary families, ranchers, and corporate plantations, the pattern of concentration carried forward almost unchanged, which is why today’s top-owner list is dominated by century-old trusts, ranches, and the state itself.
How to Find Out Who Owns a Specific Parcel
If you want to know the owner of a specific property rather than the biggest owners statewide, the Hawaii Bureau of Conveyances is the central repository for all property deeds and titles.12Bureau of Conveyances – State of Hawaii. About the Bureau of Conveyances Hawaii is one of only two states with a single statewide recording system rather than county-by-county offices. The Bureau tracks title through two parallel systems: the Regular System, a traditional deed recording method, and the Land Court system, a Torrens-style registration that guarantees title through a court certificate.
The most practical way to identify a parcel is by its Tax Map Key, a numerical code that pinpoints the island, zone, section, plat, and lot. County real property tax databases let you search by address or TMK and will show the current owner, assessed value, and tax classification. The Bureau of Conveyances offers downloadable copies of recorded documents at $1 per page, while certified copies cost $10 plus $1 per page and an additional $10 processing fee.13Bureau of Conveyances. Recording Fees Starting with the county tax records and then cross-referencing against Bureau of Conveyances documents is the standard approach.
