In 1886, the Portland & Willamette Railway Company purchased a right-of-way through John Sweek's land on Tualatin River's west bank of the opposite Bridgeport. Profiting from the sale, Sweek took advantage of the railroad's location and platted a town around the depot. He called the new town Tualatin. The City of Tualatin was incorporated in 1913 at which time an official government was formed.

Today, Tualatin has a vibrant suburban setting a short 10 miles from Portland. They have a lot to be proud of, from tree-lined streets and lush inviting parks to a productive business community. Tualatin still maintains a small town feel that about 24,000 residents call home.

Tualatin is part of the Portland-Vancouver, Oregon-WA metro area.
