Charlie Chan is a fictional Honolulu police detective created by author Earl Derr Biggers for a series of mystery novels. Biggers loosely based Chan on Hawaiian detective Chang Apana. The benevolent and heroic Chan was conceived as an alternative to Yellow Peril stereotypes and villains like Fu Manchu. Many stories feature Chan traveling the world beyond Hawaii as he investigates mysteries and solves crimes.

The Honolulu Police Department (HPD) is the principal law enforcement agency of the City and County of Honolulu, Hawaii, headquartered in the Alapa'i Police Headquarters in Honolulu CDP.
