Oran Park, a suburb in southwest Sydney within the Macarthur Region of New South Wales, Australia, is part of Camden Council. The suburb, often cited as an example of urban sprawl, has a population of 17,624 as per the 2021 census. Originally home to the Muringong, the southernmost of the Darug people, the area saw significant development in the early 19th century when John Macarthur established his property in nearby Camden to raise merino sheep.

Oran Park is notable for the Oran Park Town housing development, which replaced the Oran Park Raceway. The raceway, operational from 1962 to 2010, was a significant motorsport circuit, hosting events like the Australian Grand Prix in its pre-Formula One era and rounds of the Australian Touring Car Championship. The suburb features heritage-listed sites, including the Oran Park homestead.

The demographic profile of Oran Park is diverse, with a majority of residents born in Australia and speaking English at home. Other languages such as Punjabi, Hindi, Nepali, and Spanish are also spoken. The suburb has a mix of religious affiliations, with Catholicism being the most common, followed by no religion and Hinduism.

Oran Park is part of the north ward of Camden Council, represented by several local councilors, and falls within the federal electorate of Macarthur and the state electorate of Camden. The suburb’s transformation from a racing circuit to a residential area reflects the rapid urban development in the region, making it a modern and vibrant community within the greater Sydney area.
