Marquis de Lafayette 1
General Lafayette, 1792

Lafayette was founded in 1846 by pioneer/entrepreneur Joel Perkins, who previously had lived in Lafayette, Indiana and named it similarly for the hero of the American Revolution, Le Marquis de Lafayette (General Lafayette).

The post office was established in 1851, and the city was incorporated by the Oregon Legislative Assembly on October 17, 1878.

Lafayette was the county seat of Yamhill County from its founding until 1889, when county residents voted to move the county seat to McMinnville.


According to the United States Census Bureau, the city has a total area of 0.90 square miles (2.33 km2), all of it land.

It is located on State Highway 99W between McMinnville and Dundee.

Lock and dam

In 1900 a Yamhill River lock and dam was completed about 1.5 miles (2.4 km) downriver from Lafayette, Oregon. The lock was decommissioned in 1954. The dam was deliberately destroyed in 1963 to allow better passage for salmon on the river. The site of the lock and dam is now a county park.
