Kalawao County is a county located in the U.S. state of Hawaii. The county encompasses the Kalaupapa or Makanalua Peninsula, on the north coast of the island of Molokaʻi. The small peninsula of Kalaupapa is isolated from the rest of Molokaʻi by sea cliffs over a quarter-mile high—the only land access is a mule trail. As of the 2010 census, the population was 90, making it the least-populous county in Hawaii and the second least populous county in the United States.

Because of the small population, Kalawao County does not have the functions of other Hawaii counties. It is a judicial district of Maui County, which includes the rest of the island of Molokaʻi. The county has no elected government. Developed and used from 1866 to 1969 for settlements for treatment of quarantined persons with leprosy, it is administered by the Hawaii Department of Health. The only county statutes that apply to Kalawao County directly are those on matters of health.

Kalawao County is included in the Kahului-Wailuku-Lahaina, HI Metropolitan Statistical Area.


Kalawao County is independent of the rest of Molokaʻi, which is included as part of Maui County.

The county encompasses the Kalaupapa Settlement where the Kingdom of Hawaiʻi, the Republic of Hawaiʻi, the territory, and the state once exiled persons suffering from leprosy (Hansen's disease) from 1866 to 1969. The quarantine policy was lifted after effective antibiotic treatments were developed that could be administered on an outpatient basis and patients could be rendered non-contagious. However, many of the resident patients chose to remain, as they believed their disfigurements from the illness would make reintegration into society impossible, and the state promised that they could live there for the rest of their lives. No new patients, or other permanent residents, are admitted. Visitors are permitted only as part of officially sanctioned tours. State law prohibits anyone under the age of 16 from visiting or living there, although exceptions have been made for children seeing their relatives. The Kalaupapa National Historical Park has been established to preserve the history and environment of the county. It is coterminous with the boundaries of Kalawao County.

At the time of the 2010 census, Kalawao County had a population of 90, making its population the second smallest of any county in the United States. Only Loving County, Texas had a smaller population. According to a 2015 census esimate, Kalawao County is now the least-populated county in the United States.

Kalawao is part of the First Judicial Circuit, which includes the entire island of Oahu. For the purpose of notarization, the designated venue for the First Judicial Circuit is "State of Hawaii, City and County of Honolulu."


According to the U.S. Census Bureau, the county has a total area of 53 square miles (140 km2), of which 12 square miles (31 km2) is land and 41 square miles (110 km2) (77.3%) is water. By land area, it is the smallest county in the United States.

Kalaupapa Peninsula

Kalaupapa Peninsula contains the county's only settlement, Kalaupapa. The Kalaupapa Peninsula developed from lava that erupted from the ocean floor near Kauhako Crater and spread outward, forming a low shield volcano. This was the most recent volcanic episode on the island and of the larger East Molokaʻi shield volcano, occurring after the formation of the cliffs by erosion. Today, the dormant crater contains a small lake more than 800 feet (240 m) deep.


Traditionally, the area of Kalawao County has been composed of four ahupuaʻa. The ahupuaʻa are listed below, from west to east:

Nr. Ahupuaʻa Area
1 Kalaupapa 2.079 5.385 122
2 Makanalua 3.229 8.363 8
3 Kalawao 3.294 8.531 9
4 Waikolu 5.544 14.359 0
  Kalawao County 14.146 36.638 139

Kalaupapa ahupuaʻa is located on the west side of Kalaupapa peninsula, and includes a section of Molokaʻi's coast further west. Makanalua ahupuaʻa is a strip of land in the center of the peninsula that runs to its northern tip. Kalaupapa Airport is located in the north of Makanalua ahupuaʻa. Kalawao ahupuaʻa includes the eastern coast of Kalaupapa peninsula and Waialeia Valley to the southeast. Further southeast is virtually uninhabited Waikolu ahupuaʻa in the namesake valley.
