The 1983 America's Cup was a 12-metre class yacht racing series which pitted the defending New York Yacht Club's Liberty against the Royal Perth Yacht Club's challenger, Australia II. The September 1983 series of match races was won by Australia II, with four race wins to three, in the first successful challenge of the New York Yacht Club's 132-year defense of the Cup. The Australian syndicate's boat, skippered by John Bertrand, fought back from a 3–1 deficit to best the Dennis Conner-helmed defender, ending both the longest winning streak in sporting history and U.S. domination of the racing series.
