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 first postmaster was noted Oregon botanist Thomas J. Howell.
