Honolulu Hale, City and county government building in downtown Honolulu, United States.

Honolulu Hale is the seat of government of the City & County of Honolulu, at 530 South King Street in downtown Honolulu. Completed in 1928 in an Italianate Spanish Colonial Revival style, it has a central open courtyard, staircase and open ceiling modeled after the Bargello in Florence. Two three-story wings were added in 1951.

Architect Charles William Dickey designed and completed this government center in 1928, following the vision of Joseph Fern, who became the first mayor when the city and county unified. The building emerged during a period of rapid growth and modernization in Honolulu's development.

The name Honolulu Hale means "Honolulu House" in Hawaiian, though the word order would normally be Hale Honolulu. The interior frescoes were painted by Einar Peterson, while Mario Valdastri installed the stonework. The courtyard, staircase and open ceiling copy the Bargello in Florence. Each December the building is the center of the Honolulu City Lights display.

The building sits at 530 South King Street in downtown Honolulu and houses the mayor's office, city council chambers, and administrative departments. It remains accessible during standard business hours on weekdays and is easily reached by foot from the surrounding area.

The interior courtyard, staircase and open ceiling were modeled on the Bargello in Florence. Sculptor Isamu Noguchi's 24-foot Sky Gate stands among the surrounding landmarks, which also include ʻIolani Palace and Kawaiahaʻo Church.
