Aberdeen is a city in Grays Harbor County, Washington, United States. The population was 16,896 at the 2010 census. The city is the economic center of Grays Harbor County, bordering the cities of Hoquiam and Cosmopolis. Aberdeen is occasionally referred to as the "Gateway to the Olympic Peninsula".
Aberdeen was named after a local salmon cannery to reflect its Scottish fishing port namesake Aberdeen, and because it, too, is situated at the mouth of two rivers (Aberdeen, Scotland is bordered by the River Don to the north and the River Dee to the south).
Aberdeen was founded by Samuel Benn in 1884 and incorporated on May 12, 1890. Although it became the largest and best-known city in Grays Harbor, Aberdeen lagged behind nearby Hoquiam and Cosmopolis in its early years. When A.J. West built the town's first sawmill in 1894, the other two municipalities had been in business for several years. Aberdeen and its neighbors vied to be the terminus for Northern Pacific Railroad, but instead of ending at one of the established mill towns, the railroad skimmed through Cosmopolis and headed west for Ocosta. Hoquiam and Aberdeen citizens together built a spur; in 1895, the line connected Northern Pacific tracks to Aberdeen.
By 1900, Aberdeen had become home to many saloons, whorehouses, and gambling establishments.
