Oak Grove is an unincorporated community and census-designated place (CDP) in Clackamas County, Oregon, United States. The population was 17,290 as of the 2020 census.
History
Oak Grove was named at the suggestion of Edward W. Cornell, a member of the surveying party that platted the townsite in the 1890s. The company that was developing the property had not been able to come up with a good name for the place, and Cornell suggested "Oak Grove" after a crew ate lunch in a stand of oak trees in the northwestern part of the tract.
The area was served first from the Milwaukie post office. In 1904, Creighton post office was established, named for Susan Creighton, on whose donation land claim the office stood. Postal authorities did not name the office "Oak Grove" in order to avoid duplication. There had once been an Oak Grove post office in Josephine County. The first postmaster was noted Oregon botanist Thomas J. Howell.
Oak Grove railroad station was originally named "Center", and another station, St. Theresa, was originally named "Oak Grove". In order to prevent confusion, in 1907 the Post Office Department changed the name of the post office to "Oak Grove", and the Center railroad station was renamed to match. The railroad no longer passes through the community.
