The Lowood Airfield Circuit was a motor racing venue in Queensland, Australia. The circuit, which was used from 1946 to 1966, was located at a former wartime airfield site at Mount Tarampa, near Lowood, 72 km (45 mi) west of the state capital Brisbane. It utilised the airfield's runway for its 1.9 km (1.2 mi) long 200 m (220 yd) wide main straight and also used various taxiways and tarmac from the old hangar area. Lap distance was 4.54 km (2.82 mi).

The circuit was first used in June 1946 for the running of the Queensland Grand Prix, however it hosted only occasional meetings between then and 1956. In that year the Queensland Racing Drivers' Club took over the site, hosting their first meeting there in November and subsequently developing the circuit into Queensland's premier motor racing venue. The circuit was closed in November 1966.
