Map of Marion County, Oregon

Marion County is one of the 36 counties in the U.S. state of Oregon. It is located in the Willamette Valley, a fertile area in western Oregon. In 2020, about 345,920 people lived here, making it the 5th most populated county in Oregon.

The main city and county seat of Marion County is Salem. Salem is also the capital city of Oregon. The county was first called the Champooick District. This name came from Champoeg, a place where people often met by the Willamette River. Later, on September 3, 1849, the government of the Oregon Territory changed the name. They renamed it to honor Francis Marion, a general who fought in the American Revolutionary War. He was known as the "Swamp Fox."

History of Marion County

Marion County was officially created on July 5, 1843. It was one of the first four areas, or "districts," in the Oregon Country. The other original districts were Twality (now Washington), Clackamas, and Yamhill. In 1845, these districts were changed into counties.

When it was first formed, Marion County was much larger. It stretched all the way south to the California border and east to the Rocky Mountains. Over time, new counties like Wasco, Linn, and Polk were created. This made Marion County smaller. Its current borders were set in 1856.

In 1849, Salem became the county seat. The capital of the Oregon Territory moved to Salem in 1852 from Oregon City. There was some disagreement about where the capital should be. But in 1864, Salem was confirmed as the permanent state capital.
