Menlo was settled in 1851 as a donation land claim. The area was named for the California town of Menlo Park[2] in 1893 when the Northern Pacific Railway line was laid down through the Willapa Valley. It was shortened to Menlo when the sign was cut in half.
In 1936, Menlo's tiny Valley High School won the Washington state high school basketball championship at the University of Washington Pavilion.[3]
