Oran Park Raceway, motorsport track in Australia

Oran Park Raceway was a motor racing circuit at Narellan, southwest of Sydney, operational from 1962 to 2010. Its Grand Prix layout, extended in 1974, measured 2.625 km and formed a figure-eight with a bridge where the track crossed itself. The complex also held a motocross track, skidpan, dirt track and a 1000-foot drag strip. The site has since been redeveloped into housing.

Oran Park Raceway opened on 17–18 February 1962, built by the Singer Car Club on land from grazier Dan Cleary. The circuit grew from 1.690 km to 1.960 km and, in 1974, to a 2.625 km figure-eight Grand Prix layout with a bridge. It hosted the Australian Grand Prix in 1974 and 1977 and the Superbike World Championship in 1988 and 1989. The final race meeting was on 16 January 2010, and the track closed on 25 January 2010 before the land became housing.

The circuit closed for good on 25 January 2010, after the land was sold to the New South Wales government, and the site has since been redeveloped into housing; there is no track left to visit. The former layout, including the figure-eight Grand Prix loop with its crossover bridge, survives only as a 3D model made for driving simulators before closure.

The figure-eight Grand Prix layout, added in 1974, crossed over itself on a bridge, yet racing was still classed as anticlockwise. Before closure a 3D model of the circuit was made for driving simulators, so the track survives virtually after the housing replaced it.
