The Shelton McMurphey Johnson House, or Castle on the Hill, in Eugene, Oregon, United States, is a Victorian-era residence that is listed on the National Register of Historic Places.

The house is located at 303 Willamette Street in Eugene, at the south side of Skinner Butte, overlooking the train depot and the city's downtown.

It has undergone several modifications, including an enlargement in the 1910s for Robert McMurphey, and a remodel by Curtis and Eva Johnson in 1951 which restored its original turret.

[4] The Queen Anne-styled house is a recognizable city structure due to its high decorative carved wood, large circular tower, and green exterior paint and trim.

This 100-acre area of land that emcompasses the butte provides many recreational activities such as hiking, rock climbing, and the Shelton McMurphy Johnson house museum.
