The 2011 Touring Car Masters was Australian motor racing competition for modified Touring Cars.^[1] The series was open to cars manufactured between 1 January 1963 and 31 December 1973 and to specific models manufactured between 1 January 1974 and 31 December 1976.^[1] It was sanctioned by the Confederation of Australian Motor Sport (CAMS) as a National Series and ‘Australian Classic Touring Cars’ was appointed by CAMS as the Category Manager.^[1] The series was the fifth annual Touring Car Masters.

John Bowe (Ford Mustang) won Class C, Gary O'Brien (Holden HQ Monaro GTS) was victorious in Class B and Amanda Sparks (Porsche 911 RS) secured the Class A award.

The series was contested over eight rounds.^[2]

Each competing car was classified into one of three classes.^[1]

Series points were awarded on the following basis within each class at each race.^[1]

Bonus points were awarded to each race finisher equal to the number of cars that started a race within that class. E.g. If 14 cars started a race in Class B, then each car that finished within Class B was awarded an additional 14 bonus points for that race.^[1]

The driver gaining the highest points total from his/her best seven round results was declared the winner of that class.^[1]

Any points scored by a driver within a class were not transferred if that driver changed classes.^[1]
