King County is a county located in the U.S. state of Washington. The population was 2,188,649 in the 2017 census estimate. King is the most populous county in Washington, and the 13th-most populous in the United States. The county seat is Seattle,[1] which is the state's largest city.

King County is one of three Washington counties that are included in the SeattleTacomaBellevue metropolitan statistical area. (The others are Snohomish County to the north, and Pierce County to the south.) About two-thirds of King County's population lives in Seattle's suburbs.


The county was named after William Rufus King who was Vice President when the Washington Territory was created in 1853. On February 24, 1986, a motion to change the namesake to Martin Luther King Jr.[2] was passed by the King County Council five votes to four.[3][4] Because only the state can charter counties, the change was not made official until April 19, 2005, when the Governor signed Senate Bill 5332 into law.

The County Council voted on February 27, 2006 to adopt the proposal sponsored by Councilmember Larry Gossett to change the county's logo from an imperial crown to an image of Dr. King.[5] On March 12, 2007, the new logo was unveiled.[6] The new logo design was developed by the Gable Design Group and the specific image was selected by a committee consisting of King County Executive Ron Sims, Council Chair Larry Gossett, Prosecutor Norm Maleng, Sheriff Sue Rahr, District Court Judge Corrina Harn, and Superior Court Judge Michael Trickey.[7]

Martin Luther King Jr. visited King County for two days in November 1961.[8]
