2012 International V8 Supercars Championship

The 2012 International V8 Supercar Championship (often simplified to the 2012 V8 Supercars Championship) was an FIA-sanctioned international motor racing series for V8 Supercars. It was the fourteenth running of the V8 Supercar Championship Series and the sixteenth series in which V8 Supercars have contested the premier Australian touring car title. The championship began on 1 March at the Clipsal 500 and concluded on 2 December at the Homebush Street Circuit. The 53rd Australian Touring Car Championship title was awarded to the winner of the Drivers' Championship by the Confederation of Australian Motor Sport.

Jamie Whincup and Triple Eight Race Engineering started the season as the defending drivers' and teams' champions. At Winton, the penultimate event of the season, Whincup secured his defence of the Drivers Championship, with Triple Eight Race Engineering also wrapping up the Teams Championship. Whincup's teammate Craig Lowndes took second in the points standings from Mark Winterbottom, of Ford Performance Racing, at the final round of the series to give Triple Eight their second consecutive 1–2 finish in the Drivers Championship.
