Maui County (Hawaiian: Kalana ʻo Maui), officially the County of Maui, is a county in the U.S. state of Hawaii.

Maui County has a quasi-mayor-council form of municipal government.

Executive authority is vested in the mayor, elected by the voters on a nonpartisan basis to a four-year term (with a limit of two consecutive full terms). Legislative authority is vested in the nine-member Maui County Council. All seats in the county council have residency requirements, but all Maui County voters may vote in elections for all nine seats regardless of residence. Members of the county council are elected on a nonpartisan basis to two-year terms (with a limit of five consecutive full terms).

The mayor of Maui County is Richard Bissen, serving since January 2023. Richard Bissen formerly served as a Judge for the 2nd Hawaii State Circuit Court.

The parade banner of the county, described simply as "parade banner of the County of Maui", this banner is vertically divided light blue-light green-light blue, by red stripes, with a seal in the center.
