Washington County is one of 36 counties in the U.S. state of Oregon and part of the Portland metropolitan area. The 2020 census recorded the population as 600,372, making it the second most populous county in the state and the most populous "Washington County" in the United States. Hillsboro is the county seat and largest city, while other major cities include Beaverton, Tigard, Cornelius, Banks, Gaston, Sherwood, North Plains, and Forest Grove, the county's oldest city. Originally named Twality when created in 1843, the Oregon Territorial Legislature renamed it for the nation's first president in 1849 and included the entire northwest corner of Oregon before new counties were created in 1854. The Tualatin River and its drainage basin lie almost entirely within the county, which shares its boundaries with the Tualatin Valley. It is bordered on the west and north by the Northern Oregon Coast Range, on the south by the Chehalem Mountains, and on the north and east by the Tualatin Mountains, or West Hills.
Major roads include sections of Interstate 5 and 205, the Sunset Highway, Oregon Route 217, 47, 10, 6 and 8. Public transportation is primarily operated by TriMet and includes buses, the Westside Express Service commuter rail, and MAX Light Rail. Other transportation includes air travel at Hillsboro Airport, private airfields and heliports, and heavy rail cargo on rail lines.
History
The Provisional Legislature of Oregon created the county as Twality District on July 5, 1843. Twality was one of the original four districts of the Provisional Government of Oregon in Oregon Country along with Clackamas, Champooick (later Marion), and Yamhill counties. Columbia, later known as Hillsboro, was selected as the county seat in 1850. Washington County lost significant portions of its original area when Columbia and Multnomah counties were created in 1854. The county area was increased by 160 acres in 2014 when a section of Multnomah County was attached to Washington. The area was returned to Washington County to allow for property development.
The construction of Canyon Road to Beaverton helped Portland to consolidate its position as the primary port of Oregon, and defeat the rival efforts of settlements such as Oregon City and Milwaukie.
In November 2004, the County and the City of Beaverton agreed to a plan where the city would annex both unincorporated residential neighborhoods as well as high-value areas of land. This would result with Cedar Hills, Garden Home, Raleigh Hills, West Slope being incorporated by 2010, and the communities of Aloha, Bethany, and Cedar Mill at some point after that.
Those plans have since been put on hold after Beaverton attempted to annex Nike, Inc.'s World Headquarters, which would have increased Nike's taxes substantially. Nike successfully lobbied the legislature for a law that would prohibit their annexation for 99 years. Since that decision, annexation plans have been halted, and Washington County started urban planning to provide city-level services to the unincorporated urban areas in the county.
Geography
According to the United States Census Bureau, the county has a total area of 726 sqmi, of which 724 sqmi is land and 2.2 sqmi (0.3%) is water. It is located approximately 20 mi to the west of Portland. The Portland Metro Urban Growth Boundary (UGB) bisects the county. The county's highest point is South Saddle Mountain at 3,464 ft above sea level in the Northern Oregon Coast Range.
Most of the county is in the Tualatin Valley, formed by the Tualatin Mountains to the east and north, the Chehalem Mountains to the south, and the Northern Oregon Coast Range to the west and north. The Tualatin River, located almost entirely within the county, flows through the Tualatin Plains. The northern and western portions of the county are forested, while the remainder of the county includes urban areas, agricultural lands, and floodplains.
Waterways
The Tualatin River is the main river in Washington County. Henry Hagg Lake, southwest of Forest Grove, is the largest lake. The Willamette River lies to the east, the Columbia River to the northeast, and the Pacific Ocean to the west of the county.

Government
The county is governed by an elected board of five commissioners. The county is divided into four commissioner districts. One commissioner sits for each district, and the fifth commissioner is at-large and is the chair of the board.
Politics
Like all of the Yankee-influenced Willamette Valley and Oregon Coast, Washington County was in its pre-Depression history strongly Republican. After Oregon achieved statehood in 1859, Washington County voted for the Republican presidential nominee in every presidential election from 1860 to 1928, except in the 1912 presidential election when the county supported Progressive Party candidate and former Republican president Theodore Roosevelt. In 1932, Franklin D. Roosevelt became the first-ever Democrat to win the Washington County vote, and he repeated this success in 1936 and 1940. Between 1944 and 1988, Washington County was never won by a Democrat except in Lyndon B. Johnson's landslide victory in 1964. As recently as 1976, Washington County was the second-most Republican county in the state behind Malheur County in southeast Oregon. Gerald Ford's 17,529-vote margin of victory in the county was decisive in narrowly carrying Oregon during that year's presidential election; it was almost 10 times Ford's statewide margin of 1,713 votes.
Since the 1990s, the increasing drift of the Republican Party nationally towards the South and evangelicalism, along with urbanization, has resulted in Washington County shifting towards the Democratic Party. No Republican presidential candidate has carried Washington County since George H. W. Bush did so in 1988. In 2004, John Kerry became the first Democrat to win a majority of the county's vote since LBJ. The county swung hard to Barack Obama in 2008, who carried it with almost 60 percent of the vote and a 22-point margin over John McCain, the strongest showing for a Democrat in the county since Roosevelt. Obama won the county almost as easily in 2012, and since then, Hillary Clinton, Joe Biden, and Kamala Harris all prevailed the county by over twenty percentage points. The last Republican to win a statewide election in Washington County was Gordon H. Smith in the 2002 Senate contest. In the 2008 Senatorial election, Democrat Jeff Merkley won 48.8 percent of the county's vote (111,367) while Republican incumbent Smith won 46.5 percent (106,114), but no subsequent Republican Senate candidate has won 40 percent of the county's votes. In the 2020 presidential election, Biden hit 65.5% of the county's vote, the highest ever for a Democratic presidential nominee.
Economy
Washington County is centered on a fertile plain that attracted farmers before the first wagon trains. In 1997, orchards covered 8,403 acre of the county's lands and 1,163 acre were devoted to vineyards. Agriculture is still a major industry in Washington County, as are lumber, manufacturing, and food processing.
The development of a large electronics industry during the 1980s and 1990s is the dominating factor of the county economy, and contributing to the creation of Oregon's Silicon Forest. California-based Intel, Oregon's largest private-sector employer, has its largest concentration of employees in the county, mainly in Hillsboro. Other technology companies include Electro Scientific Industries, FEI Company, Qorvo, Tektronix, SolarWorld, Planar Systems, and EPSON.
Nike, one of two Fortune 500 corporations based in Oregon, has its headquarters in Washington County. Until it was acquired by IBM, Sequent Computer Systems was headquartered near Nike. Other companies with headquarters in Washington County include optical instruments manufacturer Leupold & Stevens, Columbia Sportswear, and Reser's Fine Foods.
