Frank C. Barnes House

The Frank C. Barnes House, also known as the Barnes Mansion, is a house located in northeast Portland, Oregon, United States, that is listed on the National Register of Historic Places. Author Beverly Cleary called the house "haunted" in her Ramona Quimby series.

Its design has been tentatively ascribed to Portland architect David L. Williams, but was more recently linked to Stokes & Zeller.
