Marion County is one of the 36 counties in the U.S. state of Oregon. The population was 345,920 at the 2020 census,^[1] making it the 5th most populous county in Oregon. The county seat is Salem,^[2] which is also the state capital of Oregon. The county was originally named the Champooick District, after Champoeg (earlier Champooick^[3]), a meeting place on the Willamette River. On September 3, 1849, the territorial legislature renamed it in honor of Francis Marion,^[4] a Continental Army general from South Carolina who served in the American Revolutionary War. Marion County is part of the Salem, OR Metropolitan Statistical Area, which is also included in the Portland-Vancouver-Salem, OR-WA Combined Statistical Area. It is located in the Willamette Valley.

Marion County was created by the Provisional Legislature of Oregon on July 5, 1843, as the Champooick District, one of the original four districts of the Oregon Country along with Twality (later Washington), Clackamas, and Yamhill counties. The four districts were redesignated as counties in 1845.

Originally, this political entity stretched southward to the California border and eastward to the Rocky Mountains. With the creation of Wasco, Linn, Polk, and other counties, its area was reduced in size. Marion County's present geographical boundaries were established in 1856.

In 1849, Salem was designated the county seat. The territorial capital was moved from Oregon City to Salem in 1852. The ensuing controversy over the location of the capital was settled in 1864 when Salem was confirmed as the state capital.

According to the United States Census Bureau, the county has a total area of 1,193 square miles (3,090 km²), of which 1,182 square miles (3,060 km²) is land and 10 square miles (26 km²) (0.9%) is water.^[5]

Marion County is among the 24 of Oregon's 36 counties that operate under a board of commissioners (BOC) of three members elected countywide to 4-year terms. In Marion County these are partisan races. Commissioners, who are full-time, salaried officials, have executive, legislative, and quasi-judicial powers (the latter in land-use cases).^[15] The Board of Commissioners serves as the governing body. The commissioners elect their chair annually; in practice, in Marion County the chair rotates annually. The BOC is responsible for accepting funds from sources outside the county, strategic planning, and enacting ordinances as needed to carry out plans and serve the public. The BOC also prepares a county budget in cooperation with the elected heads of the various departments. The BOC is required by law to appoint a Budget Officer who presents a budget to the Budget Committee composed of the Commissioners and three public members. County commissioners appoint and oversee non-elected department heads, officers, boards, and commissions.

In addition to the Board of Commissioners, the county has non-partisan positions that are elected in county-wide elections for four year terms: Assessor, Clerk, Treasurer, District Attorney, and Sheriff. Further, the county elects one Justice of the Peace (Justice Court Judge) to a six year term.^[16] These officers are accountable to the voters, rather than to the Board of Commissioners, although they work with the Commissioners in establishing a county budget. All are full-time, paid county officers.^[15]

Although Democrats took the presidential vote with pluralities in 1996, 2008, and 2020, no Democrat has carried a majority of the county since Lyndon Johnson in 1964. Marion County is one of 13 counties to have voted for Barack Obama in 2008, Mitt Romney in 2012, Donald Trump in 2016, and Joe Biden in 2020.^[a]

Agriculture and food processing are important to the county's economy, as are lumber, manufacturing, and education. Marion County is the leader in agricultural production among all other Oregon counties.^[19] Marion County has 10,640 acres (43.1 km²) planted in orchards. The marionberry was named after the county. Government, however, is the county's main employer and economic base.^{[citation needed]}

Marion County is the home of Willamette University, Corban University, and Chemeketa Community College.^[19] All of Marion County is within the Chemeketa community college district.^[20]
