Yarnell is an unincorporated historic locale in Lane County, Oregon, United States. It was located about 5 miles south of Mohawk, in the Mohawk Valley.
Yarnell was a station on the now-defunct Marcola line of the Southern Pacific Railroad. It was established in 1901, and was likely named for Jere Yarnell, a local resident listed as living in the area in the 1880 census. There was a Yarnell covered bridge about a mile north of the station that carried Hill Road over the Mohawk River. The bridge was built in 1916 and demolished in 1958. In 1915 there was a Yarnell School.
