Map of Clackamas County, Oregon

Clackamas County (pronounced CLAK-uh-muss) is one of the 36 counties in the U.S. state of Oregon. It is the third-most populated county in Oregon. In 2020, about 421,401 people lived there. Its main city, or county seat, is Oregon City.

The county gets its name from the Clackamas people. They were a group of Chinookan peoples who lived in the area when Europeans first arrived. Clackamas County is part of the larger Portland-Vancouver-Hillsboro metropolitan area. It is located in the beautiful Willamette Valley.

History of Clackamas County

Clackamas County has a long and interesting history. It was one of the first four districts created in Oregon.

Early Beginnings

On July 5, 1843, the Oregon's Provisional Legislature formed four original districts. Clackamas District was one of them. The others were Twality (now Washington), Champooick (now Marion), and Yamhill. In 1845, these districts officially became counties.

When it was first created, Clackamas County was huge! It covered parts of what are now four different U.S. states and even a part of Canada. In 1844, the Columbia River became the county's northern border.

Oregon City's Importance

Soon after the county was formed, John McLoughlin claimed land in Oregon City. He built a house there, which is now part of the Fort Vancouver National Historic Site.

Oregon City was also very important for law and order. In 1849, it had the only federal court west of the Rocky Mountains. This was even before San Francisco was fully planned out. The first official land map (called a plat) on the West Coast was filed in Oregon City in 1850. You can still see it there today!

The Willamette Meteorite

In 1902, a very large space rock, called the Willamette Meteorite, was found near West Linn. It's one of the largest meteorites ever found in North America.

Community Types

Clackamas County is special because it has different ways for its communities to be governed. Besides regular cities and rural areas, it also has "hamlets" and "villages." These are special types of communities for areas that are not officially cities.

The county created rules for hamlets and villages in 2005. For example, Beavercreek became a hamlet in 2006. The communities near Mount Hood became "The Villages at Mount Hood" in 2006.
