The 2011 L&H 500 was the ninth event of the 2011 International V8 Supercars Championship. It was held on the weekend of 16 to 18 September at the Phillip Island Grand Prix Circuit in Victoria, Australia. This was the eleventh running of the Phillip Island 500, the fourth occasion in which it filled the role of the annual 500 kilometre, two-driver V8 Supercar race, and the 21st ATCC championship race meeting at the circuit. It was also the last 500 kilometre race for V8 Supercars at Phillip Island, as the endurance race returned to Sandown Raceway in 2012, and the Phillip Island event reverted to a sprint race format with two 150 kilometre races.
