Owl's Nest Country Place, Tudor Revival estate in Greenville, Delaware, US.

Owl's Nest Country Place is an 18-acre estate at 201 Owl's Nest Road in Greenville, Delaware, built in 1915 for Eugene du Pont Jr. Its main house and three outbuildings were designed by Harrie T. Lindeberg in the Tudor Revival style, and the grounds were landscaped by Franklin Meehan and William Warner Parker. Since 1961 the property has housed the Greenville Country Club.

Eugene du Pont, Jr., son of Eugene du Pont, developed the 18-acre estate in 1915 as one of the first major Du Pont family estates in northern Delaware. Harrie T. Lindeberg designed the main house and three outbuildings in the Tudor Revival style that same year. The grounds were landscaped by Franklin Meehan and William Warner Parker, and in 1928 an Ellen Shipman-designed boxwood garden was added. The Greenville Country Club has occupied the property since 1961, and it was listed on the National Register of Historic Places in 2010.

The grounds were landscaped by Franklin Meehan and William Warner Parker, and in 1928 an Ellen Shipman-designed boxwood garden was added. The estate has housed the Greenville Country Club since 1961, so the former private grounds are now a members' golf course.

The property is private and visits require prior arrangement or specific occasion. It sits on well-accessed land in an established residential area with clear road access.

The property gained official recognition as a historic site only in 2010, despite being nearly a century old at that time. This relatively late designation shows how private estates can remain overlooked for decades before formal acknowledgment.
