The consolidated city-county was established in the city charter adopted in 1907 and accepted by the Legislature of the Territory of Hawaiʻi. As a municipal corporation and jurisdiction it manages aspects of government traditionally exercised by both municipalities and counties in the rest of the United States.

The current mayor of Honolulu County is Kirk Caldwell, who reclaimed the job from the person who defeated him in a 2010 special election, Peter Carlisle, in 2013. The county motto is Haʻaheo No ʻO Honolulu (Honolulu Pride).

Approximately 70% of the state's population lives in Honolulu County. Only Nevada has a higher percentage of its population living in its most populous county.
