The 2015 Skycity Triple Crown was a motor race for V8 Supercars held on the weekend of 19–21 June 2015.

The event was held at Hidden Valley in Darwin, Northern Territory, and consisted of two sprint races, each over a distance of 60 kilometres (37 miles) and one endurance race over a distance of 200 kilometres (124 miles).

The two sprint races were shared between Holden and Ford; Prodrive Racing Australia driver Chaz Mostert won the opening race by a second ahead of teammate, and championship leader, Mark Winterbottom,[1] while the next three placings were taken by Nissan Motorsport drivers Rick Kelly, James Moffat and Michael Caruso.

In the championship standings, the top three drivers remained the same; however, Winterbottom extended his championship lead from 12 to 95 ahead of Lowndes,[5] while Coulthard moved closer to Lowndes, trailing by 60 points.

Mostert's triple podium finish moved him up to fourth in the standings.
