The 2007 Melbourne Cup, the 147th running of Australia's most prestigious thoroughbred horse race, was run on Tuesday, 6 November 2007, going at 3:00 pm local time (0400 UTC). The race was sponsored by Emirates Airline. The winner of the race was Efficient, by a half a length, followed by Purple Moon and Mahler in third. Due to the 2007 Australian Equine influenza outbreak, believed to have been started by a horse brought into Australia from Japan, neither 2006 Melbourne Cup winner Delta Blues nor runner-up Pop Rock participated in the 2007 Melbourne Cup.
