The 2009 Island 300 was the twelfth event of the 2009 V8 Supercar Championship Series. It was held on the weekend of the November 7 and 8 at the Phillip Island Grand Prix Circuit in Victoria. The meeting was a late addition to the calendar, V8 Supercar having already raced at Phillip Island in September at the 2009 L&H 500. The round was organised after the Desert 400, set to be held at the Bahrain International Circuit, was removed from the 2009 calendar and shifted into the 2010 season in order to better link up with the newly announced round to be held at nearby Yas Marina Circuit in Abu Dhabi.
