The 2011 Skycity Triple Crown was a motor race for the Australian sedan-based V8 Supercars racing cars. It was the sixth event of the 2011 International V8 Supercars Championship. It was held on the weekend of June 17 to 19 at Hidden Valley Raceway in Darwin, Northern Territory. It was the fourteenth V8 Supercar event held at the circuit. The event hosted races 12 and 13 of the 2011 season. A 42 lap, 120-kilometre race was held on Saturday while Sunday saw a 69 lap, 200-kilometre race. Qualifying for Race 12 consisted of a 20-minute, all-in session with the fastest ten progressing to the top ten shootout. Qualifying for Race 13 was a single 20 minute, all-in session. Ford Performance Racing's Mark Winterbottom took his second consecutive pole position in qualifying for Race 12 after taking pole for the Sunday race at Winton. He was followed by the Triple Eight Race Engineering Holden of championship leader Jamie Whincup and Shane van Gisbergen of Stone Brothers Racing. These three drivers remained untroubled at the front for the majority of the race until the final safety car restart. Whincup tapped the back of Winterbottom and in response, Winterbottom slowed. This backed the field up and Winterbottom, Whincup and Van Gisbergen raced down the main straight three abreast. Towards the end of the straight, Garry Rogers Motorsport driver Lee Holdsworth pulled out of the slipstream of the top three and made it four-wide into turn one. Winterbottom and Whincup made contact which sent Whincup and Van Gisbergen off onto the grass and Winterbottom then made contact with Holdsworth before spinning in the middle of turn one and being hit by Karl Reindler. Kelly Racing's Rick Kelly emerged in the lead followed by Holdsworth, Steven Johnson and Craig Lowndes. Kelly went on to win the race, his second of the season, from Johnson and Lowndes, with Holdsworth slipping back to fourth with damaged steering. After being the top three for most of the race, Winterbottom, Whincup and Van Gisbergen finished fifteenth, ninth and seventh respectively, with each driver being penalised 25 championship points for their involvement in the incident. Drivers in the midfield also had their dramas. Rod Nash Racing driver Paul Dumbrell went off at turn five on lap one, rejoining in the lead at turn seven. Dumbrell readdressed his position on the main straight and a penalty was not applied, causing controversy
