Edgerton Park, also known as the Frederick F. Brewster Estate, is a 20-acre public park on Whitney Avenue, straddling the New Haven–Hamden town line in Connecticut.
It is site of the demolished Victorian home of Eli Whitney II, known as "Ivy Nook". In 1909, it became the estate of industrialist Frederick F. Brewster, with a new Tudor-style mansion constructed named Edgerton for its location on the edge of town. The mansion was demolished in 1964, pursuant to Brewster's wishes, after the death of his wife, and the property was donated to the city. The present landscape was designed by Robert Storer Stephenson in 1909.The property was listed as historic district on the National Register of Historic Places in 1988. In 1988, the district included seven contributing buildings, eight other contributing structures, and one contributing object.
