San Juan County is a county located in the Salish Sea in the far northwestern corner of the U.S. state of Washington. As of the 2010 census, its population was 15,769. The county seat and only incorporated city is Friday Harbor, located on San Juan Island. The county was formed on October 31, 1873, from Whatcom County and is named for the San Juan Islands, which are in turn named for Juan Vicente de Güemes, 2nd Count of Revillagigedo, the Viceroy of New Spain.
The San Juan Islands were the subject of a territorial dispute between Great Britain and the United States from 1846 to 1872, leading to the Pig War in 1859.

This county is usually even more liberal than the famously liberal King County, but does not have the reputation King County does because its population is so much smaller, and therefore its effect on elections much weaker. The only area of the county won by George W. Bush in 2004 was the Decatur Island/Blakely Island precinct, with just over 50 votes. Waldron Island's precinct voted 96.5% for John Kerry. In 2006, Maria Cantwell, the Democrat running for re-election to the U.S. Senate, won all precincts.
