The 2013 Emirates Melbourne Cup was the 153rd running of the Melbourne Cup, Australia's most prestigious Thoroughbred horse race. The race, held on 5 November 2013, at Flemington Racecourse in Melbourne, Victoria, was won by Fiorente. The horse, owned by Andrew Roberts and Barry Pang, was bred in Ireland, trained in Australia by Gai Waterhouse, and ridden by jockey Damien Oliver. It was Oliver's third victory in the event, after previous wins in 1995 and 2002, and his first start after a ten-month ban for a betting offence. Waterhouse, the daughter of Tommy J. Smith, who trained winners in 1955 and 1981, became the first Australian woman to train a winner.
