Wilderstein is a 19th-century Queen-Anne-style country house on the Hudson River in Rhinebeck, Dutchess County, New York, United States.

In 1799, the Garrettsons purchased 160 acres in Rhinebeck, New York, where they established an estate called Wildercliff, and welcomed many circuit riding Methodist preachers.

In August 1852, Thomas Suckley purchased from Mary Garrettson thirty-two acres of river-front property, which until then had served as a sheep meadow for the adjacent Wildercliff estate.

[5] Suckley and his wife Catherine Murray Bowne chose the property as a building site for their mansion, because they considered the landscape a good match for their picturesque aesthetic ideal.

The name "Wilderstein" ("wild stone" in German) was chosen by Suckley to allude to an American Indian petroglyph found nearby and reflect the site's historical significance.

The mansion commissioned for the site was a plain two-story Italianate villa designed by architect John Warren Ritch of New York.

[6] Vaux's design comprised the creation of a network of drives and trails, the positioning of specimen trees and ornamental shrubs as well as the placement of an eclectic set of out buildings such as a carriage house, a gate lodge, and a potting shed.
