Clackamas County (/ˈklækəməs/ CLAK-ə-məss) is one of the 36 counties in the U.S. state of Oregon. As of the 2020 census, the population was 421,401, making it Oregon's third-most populous county.^[1] Its county seat is Oregon City.^[2] The county was named after the native people living in the area at the time of the coming of Europeans, the Clackamas people, who are part of the Chinookan peoples.

Clackamas County is part of the Portland-Vancouver-Hillsboro, OR-WA Metropolitan Statistical Area. It is in the Willamette Valley.

Originally named Clackamas District, it was one of the four original Oregon districts created by Oregon's Provisional Legislature on July 5, 1843, along with Twality (later Washington), Champooick (later Marion), and Yamhill. The four districts were redesignated as counties in 1845. At the time of its creation, Clackamas County covered portions of four present-day U.S. states and a Canadian province. The Columbia River became the northern boundary of the county in 1844. Soon after, John McLoughlin staked a land claim in Oregon City and built a house that in 2003 became a unit of the Fort Vancouver National Historic Site.

Most of the indigenous people of the Wil-lamet Valley were forcibly removed in February 1859, to the reservation of the Confederated Tribes of Grand Ronde. Most were moved without treaty or compensation for lost lands or resources. Some 22 tribes were moved during the cold winter. It is estimated that 30% did not survive the first year. The tribes eventually prospered, but outside of Clackamas County. They also never received any revenue or compensation from the logging of their homeland forests.

In addition, the Tribes of the Cascades Mountains were isolated to a Reservation after the signing of a treaty in 1859. Confederated Tribes of Warmsprings was established and remains a strong and vital player in actions that concern the Federal forests of the Cascades Range.

Oregon City was also the site of the only federal court west of the Rockies in 1849, when San Francisco, California, was platted. The plat was filed in 1850 in the first plat book of the first office of records on the West Coast and is still in Oregon City.

Around 1900, the spa and resort at Wilthoit Springs was a popular tourist destination.^[3] In 1902, the Willamette Meteorite was recovered from a field near present-day West Linn.

According to the United States Census Bureau, the county has a total area of 1,883 square miles (4,880 km²), of which 1,870 square miles (4,800 km²) is land and 12 square miles (31 km²) (0.7%) is water.^[4]

The county includes parts of two national forests: Mount Hood National Forest and Willamette National Forest.

Several of the county's cities extend into other counties. Lake Oswego and Milwaukie include areas in Multnomah County. Lake Oswego, Rivergrove and Wilsonville include areas in Washington County. The cities of Portland and Tualatin extend into Clackamas County from Multnomah and Washington counties respectively.

In Clackamas County, hamlets and villages are models of local land use governance for unincorporated areas. The four hamlets in Clackamas County are Beavercreek, Molalla Prairie, Mulino, and Stafford. The county's only village is the Villages at Mount Hood.

• Molalla Prairie

• Bissell – named for W. S. Bissell, U.S. Postmaster General from 1893 to 1895.^[14] Bissell had its own post office from at least 1899 to 1923.^[15][16]

Clackamas County is the first county in Oregon to have four models of governance for its communities. Like the rest of Oregon, it has cities (which are formally incorporated) and rural communities (some of which for federal purposes are considered census-designated places).

After the completion of a process that began in late 1999, the county adopted an ordinance on August 11, 2005, which defined hamlets and villages. By the November 30, 2005, deadline, three communities had submitted petitions to be designated as such. Boring petitioned to become a village, but the application was rejected in a town hall referendum in August 2006. The communities along U.S. Route 26 near Mount Hood from Brightwood to Rhododendron petitioned to become "The Villages at Mount Hood", and it was approved by residents in May 2006. Beavercreek petitioned to become a hamlet, and was recognized as such in September 2006.

Since the county's creation, agriculture, timber, manufacturing, and commerce have been the principal economic activities. Mount Hood, the only year-round ski resort in the United States and the site of Timberline Lodge, is a major attraction for recreation and tourism, offering outdoor recreation activities from skiing and rafting to fishing and camping.

The county supports the Library Information Network of Clackamas County. The urban areas of the county are also served by Metro.
