Washington County is a
county located in the
U.S. state of
Oregon. Originally called Twality, the Territorial Legislature
renamed this county for the first president of the United States,
George Washington on
September 3,
1849. As of the
2000 census, Washington County is home to 445,342 residents. The
county seat is
Hillsboro.
Washington County is centered on a fertile plain that attracted farmers before the first
wagon trains. In 1997, orchards covered 8,403 acres (34 km²) of the county's lands and 1,163 acres (4.7 km²) were devoted to vineyards.
The development of a large electronics industry during the last two decades is the dominating factor of the economy of this county.
Intel, Oregon's largest private employer, has here its largest concentration of employees outside of its
California home. Agriculture is still a major industry in Washington County, as are lumber, manufacturing, and food processing.
Washington County is the location for the corporate headquarters of
Nike, the only corporation based in Oregon large enough to be included in the
Fortune 500 list. Until it was acquired by
IBM,
Sequent Computer Systems was headquartered right next door to Nike. The facility is now host to a number of software groups for IBM, including one of its
Linux Technology Centers.
Located to the west of
Portland, this county has a total area of 1,881
km² (726
mi²). 1,874 km² (724 mi²) of it is land and 7 km² (3 mi²) of it (0.36%) is water.

The Provisional Legislature created Washington County as Twality District on
July 5,
1843, as one of the original four districts of the Oregon territory along with
Clackamas, Champooick (later
Marion), and
Yamhill counties. Columbia, later known as
Hillsboro, was selected as the county seat in 1850. Washington County obtained its present boundaries in 1854 with the creation of
Columbia County to the north and
Multnomah County to the east.
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 as
Oregon City and
Milwaukie.
Washington county has been a stronghold of the
Republican Party, who have consistently registered a majority of voters as members ever since its creation, despite Washington County's evolution from a farming economy to a suburb of
Portland.
In November of 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.
