Dunthorpe is an affluent, unincorporated suburb of Portland, Oregon, United States. It is located just south of the Portland city limits and north of the Multnomah County line on the west side of the Willamette River. Lewis & Clark College, Tryon Creek State Park, and Lake Oswego are nearby.
In January 1916, William M. Ladd's Ladd Estate Company purchased 215 acres (0.87 km2) from the soon to be dissolved Oregon Iron & Steel Company for $1. The company drafted very specific provisions for the Dunthorpe development, including: Only residential buildings were allowed, except for outbuildings to house domestic animals; Swine and goats were prohibited; The minimum cost of a house was $3000; and the sale of "intoxicating liquor" was prohibited.

Museums and other points of interest
One of the notable attractions of the area is the Elk Rock Gardens of the Bishop's Close, an estate which consists of 13 acres (53,000 m2) on a high bluff on the western bank of the Willamette River. The property includes approximately 6 acres (2.4 ha) of cultivated English-style gardens that were designed by the New York firm of Olmsted and Son, who also designed Central Park in New York City. The garden is open to the public seven days a week and is widely known for the many varieties of magnolias as well as for examples of many other native and exotic plants.

As a community, Dunthorpe was historically anchored by Riverdale Grade School. In the early 1990s, the Oregon legislature decreed that all school districts should have both primary and secondary schools, and expected smaller school districts like Riverdale to merge. While an old grade school was purchased and renovated for use as Riverdale High School, high school students were bussed to nearby Marylhurst University in the neighboring city of West Linn, where space was leased by the school district. The high school moved into its permanent building, a renovation and expansion of an existing but unused public school structure, in September 2002. In November 2008, the voters of Riverdale School District passed a measure authorizing the District to issue bonds in an amount up to $21.5 million to renovate and expand the existing grade school building. In July 2009, the original grade school was demolished. The building was rebuilt in the style of the original in 2010.
