Oran Park, Heritage site in Macarthur Region, Australia

Oran Park is a two-storey Victorian Italianate house with wrap-around verandahs, a rear basement and an octagonal tower, built from 1837 to 1946 at 112–130 Oran Park Drive, Oran Park. Its coach house dates from c. 1837, and the house was later converted to Georgian Revival style.

The property was granted by Governor Macquarie in 1815 to Captain William Douglas Campbell, and saw many changes of ownership afterward. The buildings were modified several times during the 1800s.

The name Oran Park was used for the estate from the Campbell era, and the house later served as a golf clubhouse when Edward Star laid out an 18-hole course and trotting track in the 1960s. Lionel Dawson-Damer, who bought the property in 1969, kept his historic car collection in the stables and outbuildings.

Oran Park house is a private residence at 112–130 Oran Park Drive, Oran Park, and is not open to the public; the house and grounds can be seen only from the street. The property was added to the New South Wales State Heritage Register on 5 March 2015, so any works need heritage approval. The former raceway site west of the property is separate land.

The property is surrounded by Mediterranean cypress trees and Bunya pines that mark historical pathways and driveways across the grounds. These trees give the place a distinct appearance and show the landscaping choices of earlier times.
