2020 Supercars Championship

The 2020 Supercars Championship (known for commercial reasons as the 2020 Virgin Australia Supercars Championship) was a motor racing series for Supercars. It was the twenty-second running of the Supercars Championship and the twenty-fourth series in which Supercars have contested the Australian Touring Car Championship, the premier title in Australian motorsport. Due to disruption caused by the COVID-19 pandemic, a number of rounds were rescheduled or cancelled.

The series reverted to having only two manufacturers, Ford and Holden, for the first time since 2012 with Nissan no longer being represented on the grid.

Scott McLaughlin successfully defended his drivers' championship with one event remaining, winning the title for the third consecutive year. DJR Team Penske successfully defended the teams' championship. Ford successfully defended the manufacturers' championship.

Holden was represented by factory-backed team Triple Eight Race Engineering.

The following teams and drivers competed in the 2020 championship.

Tekno Autosports relocated to Western Sydney and expanded to a two-car operation under the Team Sydney by Tekno brand. A second Racing Entitlement Contract (REC) was acquired from Supercars management. It entered two Triple Eight-built Holden ZB Commodores.

Brad Jones Racing expanded to a three-car team, after acquiring an REC that was formerly owned by Britek Motorsport and had been leased to Matt Stone Racing. Brad Jones Racing continued to operate a fourth car on behalf of Tim Blanchard Racing.

Kelly Racing scaled down from a four-car team racing Nissan Altimas to a two-car team with Ford Mustangs. Two of the team's RECs were purchased by Team 18 and Matt Stone Racing, with both expanding to two car entries. Matt Stone Racing acquired a second REC from Garry Rogers Motorsport to replace the one it had been leasing from Britek Motorsport. Team principal Garry Rogers cited escalating costs of competing and a model that required them to purchase parts rather than develop them as the reasons for his decision to withdraw. Rogers' team later returned to the championship with a single wildcard for the Bathurst 1000 – signing Super2 Series drivers Tyler Everingham and Jayden Ojeda. Nathan Herne from the Australian TA2 Racing Series was originally signed in Ojeda's place however his entry was blocked as Motorsport Australia denied him of the required licence.
