Hoover–Minthorn House, Presidential historic house museum in Newberg, United States.

The Hoover–Minthorn House is a two-storey Italianate house with an L-shaped plan and a hipped roof, built in 1881 in Newberg, Oregon. A shed is attached to its southwest corner, and a porch stands before the entrance door. The upper windows have a frieze-like band of flat plates, and both rows of windows end in a simple architrave. It is now a house museum furnished with late 19th-century period pieces, including the bedroom furniture Hoover used as a boy.

Jesse Edwards, a Quaker merchant, built the house in 1881 as the first residence on his new farm; it is the oldest building still standing in Newberg. In 1884 it was sold to Henry John Minthorn, who had moved from West Branch, Iowa, in 1882 and directed a nearby Indian school and then the Friends Pacific Academy. The Minthorns took in their orphaned nephew Herbert Hoover in 1884; he attended the Quaker school from September 1885. Minthorn resigned as school director in 1889 and moved the family to Salem, Oregon.

The house is owned and operated as a museum by the Oregon chapter of The National Society of the Colonial Dames of America, not by a Quaker body. Its rooms hold late 19th-century period furnishings, including the bedroom furniture Herbert Hoover used as a boy, and the property is listed on the National Register as the Dr. Henry J. Minthorn House.

Visits are guided, so it is a good idea to check current opening days before making the trip to Newberg. The rooms are small and tours take only a few people at a time, so arriving early gives you more flexibility.

The house was listed on the National Register of Historic Places on 19 December 2003 under the name Dr. Henry J. Minthorn House, also known as Herbert Hoover House. The Minthorns left Newberg in 1889, when Henry John Minthorn resigned as school director and moved the family to Salem, Oregon.
