Willamina is a city in Polk and Yamhill Counties in the U.S. state of Oregon. The population was 2,239 at the 2020 census.

The Yamhill County portion of Willamina is part of the Portland–Vancouver–Beaverton, Metropolitan Statistical Area, while the Polk County portion is part of the Salem Metropolitan Area.

Willamina was named after Willamina Creek, which in turn was named for early settler Willamina Williams shortly after she fell off of her horse and into the creek. Williams was born Willamina Craig in 1817 in Ohio. She married James Maley in 1837 and the couple came to Oregon in 1845 with James' daughter. While looking for land to settle, the family came across a tributary of the South Yamhill River and named it for Mrs. Maley. James Maley died in 1847, and Willamina married Enos Williams in 1848. They settled in what is now Amity.

Willamina post office was established in 1855 on the James Brown land claim, about a mile east of present-day Willamina. The office moved in 1863 about two miles west to the Jeremiah Lamson land claim. In 1866, the office was moved and renamed to present-day Sheridan. In 1878, a new Willamina post office was established; it operated from December 1880 to March 1891 just over the county line in Polk County. A gristmill and sawmill were established in 1878. The townsite was platted in 1879 and Willamina incorporated in 1903. At that time the city had 200 residents.

According to the United States Census Bureau, the city has a total area of 0.96 square miles (2.49 km), of which 0.92 square miles (2.38 km) is land and 0.04 square miles (0.10 km) is water.

The city lies near the intersection of Oregon Route 18, Oregon Route 18 Business, and Oregon Route 22 next to the South Yamhill River. The communities of Shipley and Sheridan are to the east, and Valley Junction is to the west.

Willamina experienced an economic boom in 1907, when a brick-making company, the Pacific Face Brick Company, moved from Newberg and opened the Willamina Clay Products plant. The Sheridan and Willamina Railroad was built to the city because of the brick plant, which ran for 82 years. Bricks made at Willamina Clay Products were used in the Portland Art Museum, Jackson Tower, and Lloyd Center in Portland, and the Yamhill County Courthouse. The brick plant closed in 1974; the buildings were razed in 1976. The red clay for the company's products came from Newberg, the white clay from Willamina, and the buff clay from Buena Vista.

The other mainstay of the city's economy is the timber industry, and when the Pacific Plywood Corporation opened a plant in 1939, the city's population tripled. Willamina became known as "The Little Town with the Big Payroll". As of 2002, the city's largest employers were Spirit Mountain Casino in nearby Grand Ronde, Hampton Lumber Company, Willamina School District, Maben Trucking, and Eddy Trucking.

Willamina is served by the Willamina School District, including Willamina High School.

Willamina was formerly served by The Sun, Sheridan's weekly newspaper, which ceased publication in 2014. Currently, Willamina is served by the News-Register, a county-wide publication based in McMinnville.

The Sheridan and Willamina Railroad was founded in 1907 and became part of the Southern Pacific Railroad's Willamina Branch in 1913. The independent short line company Willamina and Grand Ronde Railroad (W&GR) extended the line south and west from Willamina to Grand Ronde in 1922; the W&GR changed ownership several times. It was purchased by the Willamette Valley Railway in 1980. Today the lines east and west of Willamina are owned by the Portland and Western Railroad, although the portion of the line from Fort Hill to Grand Ronde is abandoned.
