Sherwood is a city in Washington County, Oregon, United States.As of the 2010 census, Sherwood had a population of 18,194 residents.
What is now the Sherwood area was originally inhabited by the Atfalati band of the Kalapuya nation. The first significant wave of United States emigrants arrived in 1842.Native Americans were relocated to reservations after the Donation Land Claim Act of 1850–55 gave American citizens exclusive ownership of these lands. The name "Sherwood" arose from a declination of naming the town "Smock Ville" after its co-founders James Christopher and Mary Ellen Smock. In 1885, the Smocks gave a right-of-way on their property to the Portland and Willamette Valley Railway. The Smocks platted the town in 1889, the same year rail service began. Tradition has it that no one, not even the town's founders, liked the name "Smock Ville," and so a public meeting was held to rename the town. Robert Alexander, who was both a local resident and prominent businessman, suggested the name "Sherwood." According to post office records, Alexander was from Sherwood, Michigan, and also said the forest which surrounded the city was like Sherwood Forest in England. The U.S. Postal Department began sending mail to the Town of Sherwood, Oregon on July 5, 1891. Smock was the first postmaster. The Town of Sherwood was incorporated under Oregon Senate Bill 36 in 1893.
