Dayton is a city in Yamhill County, Oregon, United States. The population was 2,534 at the 2010 census.


The city was founded in 1850 by Andrew Smith and Joel Palmer. Palmer, who also served as superintendent of Indian affairs for Oregon, built a flour mill there. Dayton was named for Smith's hometown, Dayton, Ohio. Dayton post office was opened in 1851, with Christopher Taylor serving as postmaster.

There are many historic landmarks throughout the city. The oldest standing structure is the Joel Palmer House, built in 1852 or 1857. It has been on the National Register of Historic Places since March 16, 1987, and has been painstakingly restored. Since 1996 it has been home to a four-star restaurant of the same name as the historic house.

Nearby, in Courthouse Square Park, is the Fort Yamhill Block House, which was brought to Dayton in 1911 to prevent its demolition. The structure had been built by Willamette Valley settlers on Fort Hill in the Grand Ronde Valley in 1855 and 1856. John G. Lewis, a citizen of Dayton, secured permission from authorities to move the logs to Dayton, where they were reassembled.


Dayton is located in the Willamette Valley, approximately 25 miles southwest of Portland and seven miles east of McMinnville.

According to the United States Census Bureau, the city has a total area of 0.84 square miles (2.18 km2), all of it land.

Dayton is a rural community, with many people involved in agriculture such as vegetable, berry, nut, nursery plants, wheat production and dairy farming. The vineyards and wineries located in the Willamette Valley AVA and the Dundee Hills AVA are an increasing source of direct economic activity as well as a source of visitors to the city.


Dayton is served by three signed Oregon state highways and one unsigned state highway:

  • Signed highways
    • Oregon Route 18
    • Oregon Route 221
    • Oregon Route 233, which travels as one road with State Route 18 between Lafayette Highway to the west and Oregon Route 99W to the east.
  • Unsigned highway
    • Oregon Route 154 (SE Lafayette Highway) is assigned this route number south of its intersection with State Highway 233.

Prior to the construction of Highway 18 as a limited-access bypass of Dayton and McMinnville, Highway 233 continued east on its old route (SE Amity-Dayton Highway) into downtown Dayton, where it was named Ferry Street. The highway crossed the Yamhill River via ferry to the northeast side of the river at what is now called Alderman Park. There, Highway 233 continued northeast along SE Kreder Road to its northern terminus at what was then numbered as US Route 99W. During this period, the northern terminus of Highway 221 was located at its intersection with Ferry Street.


Dayton has three schools within the Dayton School District: Dayton Grade School, Dayton Middle School and Dayton High School. The school mascot is the Pirate.
