Hawaiʻi County is a county in the U.S. state of Hawaii in the Hawaiian Islands. It is coterminous with the Island of Hawaii, often called the "Big Island" to distinguish it from the state as a whole. As of the 2010 Census the population was 185,079. The county seat is Hilo. There are no incorporated cities in Hawaii County (see Hawaii Counties). The Hilo Micropolitan Statistical Area includes all of Hawaii County. Hawaii County has a mayor–council form of government. Hawaii County is the largest county in the state in terms of geography.
Hawaii County is one of seven counties in the United States to share the same name as the state they are in (the other six are Arkansas County, Idaho County, Iowa County, New York County, Oklahoma County, and Utah County). 
Hawaiʻi County has a total area of 5,086.70 square miles (13,174.5 km2); 4,028.02 square miles (10,432.5 km2) is land and 1,058.69 square miles (2,742.0 km2) is water  (mostly all off the ocean shoreline but counted in the total area by the U.S. Census Bureau).

Executive authority is vested in the mayor of Hawaii County, who is elected for a four-year term. Since 2004, the election by the voters has been on a nonpartisan basis. In 2016, Harry Kim was elected mayor, succeeding Billy Kenoi, who had served a two-term limit.  Legislative authority is vested in a nine-member County Council. Members of the County Council are elected on a nonpartisan basis to two-year terms from single-member districts.  As of December 2016, Hawaiʻi County Council has a female supermajority for the first time, with six women and three men. 
Administrative districts were originally based on the traditional land divisions called Moku of Ancient Hawaii. Some more heavily populated districts have since been split into North and South districts to make them more comparable on a population basis.
The number following each district is the Tax Map Key (TMK) number, used to locate state property information. They are assigned in a counter-clockwise order beginning on the eastern side of the island. 
|Hawaiʻi County||4028.02||148677||6 moku|
County council districts do not directly match the property tax districts because of the variation in the population density of voters in urban areas to rural areas; Hilo & Kailua (Kailua-Kona) towns are densely populated areas, while other districts such as Kaʻū, Puna, Hāmākua, and North & South Kohala are more sparsely populated. 
Several government functions are administered at the county level that are at the state or municipal level in other states. For example, the county has its own office of liquor control. 
Hawaii Department of Public Safety previously operated the Kulani Correctional Facility in Hawaii County, on the Island of Hawaii.  In 2009, the Hawaii Department of Public Safety announced that Kulani Correctional Facility would close.
