Woodburn is a city in Marion County, Oregon, United States. Incorporated in 1889, the community had been platted in 1871 after the arrival of the railroad. The city is located in the northern end of the Willamette Valley along Interstate 5 between Portland and Salem. Oregon routes 211, 214, 219, and 99E also serve the city, as does a freight rail line from Union Pacific.
Woodburn is part of the Salem Metropolitan Statistical Area, and with a population was 24,080 at the 2010 census, it is the third most populous in that metropolitan area after Salem and Keizer. Those who identify as Hispanic or Latino made up a majority of the population in the city. The Woodburn area also has a significant population of Russian Orthodox Old Believers.
Originally, the area around Woodburn was inhabited by Native Americans of the Kalapuya tribes. After the Provisional Government of Oregon set-up land claims in the Oregon Country, the United States annexed much of the Pacific Northwest and established the Oregon Territory in 1848. Congress then passed the Donation Land Claim Act in 1850, and many earlier land claims became donation land claims.
