The Adelaide 500 is an annual motor racing event for Supercars held on the streets of the east end of Adelaide, South Australia between 1999 and 2020 and again from 2022. The event uses a shortened form of the Adelaide Street Circuit, the former Australian Grand Prix track. The event is still colloquially known as the Clipsal 500 or simply "Clipsal" after its former longtime sponsor. By attendance and number of events, the Adelaide 500 is the biggest multiple-day car race in Australia.

The Supercars Championship currently known as the Repco Supercars Championship under sponsorship, is a touring car racing category in Australia and New Zealand, running as an International Series under Fédération Internationale de l'Automobile (FIA) regulations, governing the sport.
