Kentuck Knob (also known as the Hagan House) is a house in Stewart Township, near the village of Chalkhill, in Fayette County, Pennsylvania, United States. Designed by the architect Frank Lloyd Wright in the Usonian style, the residence was developed for I. N. Hagan, the owner of a local ice-cream firm, along with his wife Bernardine. it is built on the southern slope of a knoll known as Kentuck Knob, overlooking the Youghiogheny River gorge. The name of the house and knoll is derived from an 18th-century settler who was planning to move to Kentucky. The house is designated as a National Historic Landmark.

I. N. and Bernardine Hagan had learned of Wright's work through Edgar J. Kaufmann, a businessman who had hired Wright to design the Fallingwater house in Fayette County. The Hagans purchased 79 acres (32 ha) of land near Uniontown, Pennsylvania, in July 1953 and asked Wright to design them a Usonian home for them. Despite being busy with multiple other projects, Wright agreed to design a house at Kentuck Knob, which was completed in 1956. The Hagans lived at Kentuck Knob until 1986, when they sold the property to Peter Palumbo, Baron Palumbo. The house was damaged by a fire shortly afterward, and the Palumbo family renovated the house afterward. Kentuck Knob has been open to the public for tours since 1996, and a visitor center there was completed in 2003.

The estate, accessed by a driveway from Pennsylvania State Route 2010, includes approximately 8,800 trees and a sculpture garden for the Palumbo family's art collection. The house itself is made of redwood and locally-quarried stone, with an overhanging copper roof and two exterior terraces. It is laid out around a hexagonal floor plan, which consists of two wings that partially surround a courtyard, converging at a hexagonal core. The interior covers 2,300 square feet (210 m²) and consists of seven rooms in an open plan arrangement. The kitchen, within the house's core, is surrounded by a living room to the west and a dining room to the west. Extending northeast of the core are three bedrooms, which are partially embedded into the hillside. The house's carport, which includes an art studio, is attached to the bedroom wing.
