Multnomah County ( //) is one of 36 counties in the U.S. state of Oregon. Though smallest in area, it is the most populous as its county seat, Portland, is the state's largest city. In 2010, the county's population was 735,334. The county was likely named after Native American people first recorded in the journals of the Lewis and Clark Expedition, Mulknomans, who lived in a village on the east side of present-day Sauvie Island. (An alternative theory holds that Multnomah is a corruption of nematlnomaq, meaning down river.)
Multnomah County (the thirteenth in Oregon Territory) was created on December 22, 1854, formed out of the eastern part of Washington and the northern part of Clackamas counties. Its creation was a result of a petition earlier that year by businessmen in Portland complaining of the inconvenient location of the Washington County seat in Hillsboro and of the share of Portland tax revenues leaving the city to support Washington County farmers. County commissioners met for the first time on January 17, 1855.
There has long been a movement to merge the county with the city of Portland. In 1968, the Oregon Legislative Assembly referred a bill, Ballot Measure 5, to voters that would amend the state constitution to allow for consolidated city-county governments when the population is over 300,000. The 1968 voters' pamphlet noted that Multnomah County would be the only county in Oregon affected by the measure and voters approved the referendum in the 1968 general election. Since the approval of Measure 5 in 1968, an initiative to merge the county with Portland has been considered and placed on the county ballot several times. The merger would have formed a consolidated city-county government like that of San Francisco, California. None of these proposals has been approved.
In the 2000 presidential election, Multnomah played a decisive role in determining the winner of the state's electoral votes. Al Gore carried the county by more than 104,000 votes, enough to offset the nearly 100,000-vote advantage that George W. Bush had earned among Oregon's 35 other counties. The Democratic tilt was repeated in 2004, when John Kerry won by 181,000 votes, and in 2008 when Barack Obama won by 204,000 votes.
In February 2001, the Multnomah County Board of Commissioners unanimously accepted the recommendation of the Library Advisory Board and authorized the library to enter into a lawsuit to stop the Children's Internet Protection Act. The US Supreme Court ultimately decided in 2003 that the law was constitutional in US v. ALA. However, the library chose to turn down $104,000 per year of federal funding under CIPA to be able to continue to offer unfiltered Internet access.
Faced with decreasing government revenues due to a recession in the local economy, voters approved a three-year local income tax (Measure 26-48) on May 20, 2003 to prevent further cuts in schools, police protection, and social services. Multnomah County was one of the few local governments in Oregon to approve such a tax increase.
On March 2, 2004, Multnomah County Chair Linn announced the county would begin granting licenses for same-sex marriages, pursuant to a legal opinion issued by its attorney deeming such marriages lawful under Oregon law. Her announcement was supported by three other commissioners (Serena Cruz, Lisa Naito & Maria Rojo de Steffey), but criticized by Lonnie Roberts, who represents the eastern part of Multnomah county and was left out of the decision. Within a few days, several groups joined to file a lawsuit to halt the county's action; see Same-sex unions in Oregon.

The principal industries of Multnomah County are manufacturing, transportation, wholesale and retail trade, and tourism. Since Oregon does not have a sales tax, it attracts shoppers from southwest Washington.
The Port of Portland, established in 1891 and combined with the City of Portland's Commission of Public Docks in 1971, ranks third in total waterborne commerce on the West Coast, and 31st in the nation for total tonnage according to the 2009 American Association of Port Authorities' Port Industries Statistics. Portland is one of the five largest auto import ports in the nation and is the West Coast's leading exporter of grain and lumber. The Port of Portland is also responsible for Portland International Airport in the Northeast section of Portland, the Troutdale Airport a few miles east of PDX in Multnomah County, the Hillsboro Airport to the west in Washington County, and Mulino Airport to the south in Clackamas County.
The Multnomah County Library has a small impact on the county budget: the county library, which supplies Internet service to area libraries, turns down $104,000 per year in federal funding starting in 2004, to obviate the need to comply with the Children's Internet Protection Act so as to maintain unfiltered Internet access.
The county is home to a number of Portland-area attractions and venues, including Oregon Museum of Science and Industry, Portland Art Museum, Memorial Coliseum, Oregon Convention Center, Rose Garden, Washington Park, Oregon Zoo, International Rose Test Garden, Portland Classical Chinese Garden, Portland Japanese Garden, and Pittock Mansion.
The county was the birthplace of the Multnomah Community Ability Scale, used in mental health programs throughout the U.S.
