The 2017 America's Cup was the 35th staging of the America's Cup yacht race. The challenger, Emirates Team New Zealand, won by a score of 7 to 1 over the defender, Oracle Team USA. It was held on the Great Sound in Bermuda from June 17 to June 26. The races were conducted using hydrofoiling AC50 America's Cup Class yachts, which are slightly larger than the AC45F yachts used in the 2015–16 America's Cup World Series.
