Grays Harbor County is a county in the U.S. state of Washington. As of the 2020 census, the population was 75,636.^[1] Its county seat is Montesano, and its largest city is Aberdeen.^[2] Grays Harbor County is included in the Aberdeen Micropolitan Statistical Area.

The county is presently named after a large estuarine bay near its southwestern corner. On May 7, 1792, Boston fur trader Robert Gray crossed the bar into a bay which he called Bullfinch Harbor, but which later cartographers would label Chehalis Bay, and then Grays Harbor.^[3]

The area that now comprises Grays Harbor County was part of Oregon Territory in the first part of the nineteenth century. On December 19, 1845, the Provisional Government of Oregon created two counties (Vancouver and Clark) in its northern portion (which is now the state of Washington). In 1849, the name of Vancouver County was changed to Lewis County, and on April 14, 1854, a portion of Lewis County was partitioned off to become Chehalis County.^[4] This county's boundaries have not changed since its creation, but on June 9, 1915,^[5] its name was changed to Grays Harbor County to eliminate confusion with the town of Chehalis in Lewis County.^[6]

According to the United States Census Bureau, the county has a total area of 2,224 square miles (5,760 km²), of which 1,902 square miles (4,930 km²) is land and 322 square miles (830 km²) (14%) is water.^[7]
