The office was formerly named "Amos" and was located two miles south of London, on a tributary of the Coast Fork Willamette River. Amos post office was founded in 1898 and ran until its move to London. It was named for John Amos Sutherland, son of postmaster John Sutherland. Levi Geer developed a mineral spring here, and it is unknown why he named the place "London", but when the post office moved to the community, it was renamed after the new location. Geer and Sutherland operated a general store in which the post office was located for a time.
