Kalawao County is a unique, sparsely populated county in the State of Hawaii. It consists largely of the Kalaupapa or Makanalua Peninsula on the north shore of the island of Molokaʻi. The county is distinct from the rest of Molokaʻi, which is governed as part of another county, and it is often noted for being the smallest U.S. county by population.

The peninsula is geographically isolated: steep sea cliffs separate it from the island interior, and traditional access routes include the historic mule trail and limited air service. The landscape includes coastal bluffs, small valleys, and shoreline plain that once supported compact settlements. This isolation shaped both daily life and the area’s use as a remote care facility.

Kalawao County's modern identity grew from its role as a place of quarantine in the 19th and early 20th centuries. People diagnosed with Hansen's disease (historically called leprosy) were sent to the peninsula under territorial and later state policies. Over time, hospitals, residences, and community institutions were established to house and treat residents who were separated from the rest of the islands.

Today the county has no traditional municipal government structure. Many public functions and services are provided by state agencies and federal partners rather than by local elected officials. Management and preservation efforts involve state health authorities as well as the National Park Service, which now administers much of the peninsula as a protected area and historical park.

Kalawao County's story combines geography, public health policy, and preservation. Visitors and researchers are drawn by the peninsula's dramatic terrain and the human stories preserved there, while authorities continue to balance access, commemoration, and the needs of the small resident community.
