Vancouver is a city on the north bank of the Columbia River in the U.S. state of Washington. It is the largest suburb of Portland, Oregon. Incorporated in 1857, Vancouver had a population of 161,791 as of the 2010 U.S. census, making it the fourth-largest city in Washington state. Vancouver is the county seat of Clark County and forms part of the Portland-Vancouver metropolitan area, the 23rd largest metropolitan area in the United States. Originally established in 1825 around Fort Vancouver, a fur-trading outpost, the city is located on the Washington–Oregon border along the Columbia River, directly north of Portland. In 2005, Money magazine named it No. 91 on its list of best places in America to live. In 2016, WalletHub ranked Vancouver the 89th best place in the U.S. for families to live.
Vancouver shares its name with the larger city of Vancouver in southern British Columbia, Canada, approximately 300 mi (480 km) to the north. Both cities were named after sea captain George Vancouver, but the American city is older. Vancouver, British Columbia was incorporated 29 years after the incorporation of Vancouver, Washington, and more than 60 years after the name Vancouver was first used in reference to the historic Fort Vancouver trading post on the Columbia River.
