Farmington is a town in Marion County, West Virginia, United States.

The community was named for the fact a large share of the first settlers were farmers.

The area would later be incorporated in Marion County as the town of Farmington in 1896, but was earlier known as Willeyvile, Willeytown, and Underwood.

The town was close to mine Number 08 of Jamison Coal and Coke Company.

Preschool through grade three attend Fairview Elementary School and grades four through eight attend Fairview Middle School, both in nearby Fairview, while students in grades nine through twelve attend North Marion High School, which is located approximately 2 miles (3.2 km) east of Farmington on US Route 250 and has a Farmington mailing address.

Adjacent to North Marion High School is the Marion County Technical Center, which houses vocational and career tech programs available to high school students from the entire district.

It was closed due to structural issues caused by mine subsidence, which affected several other properties in town during the 1970s.

The racial makeup of the town was 96.90% White, 1.81% African American, and 1.29% from two or more races.
