Carlton is a city in Yamhill County, Oregon, United States. According to the 2000 United States Census, the municipality population was 1,514. The 2007 estimate is 1,755 residents.
The origin of Carlton's name is disputed. An ex-county commissioner claims that the name was derived from Wilson Carl, whereas A. E. Bones, postmaster at Carlton, stated in a 1925 letter that it was named for John Carl, Sr., at the request of R. R. Thompson. These men may have been part of the same family.
Carlton post office was established in 1874, with F. J. Fryer serving as its first postmaster.
