context_page_description: The 2017 Louis Vuitton Challenger's Trophy was a sailing competition held to determine the challenger in the 2017 America's Cup. The races ran from 5 to 12 June 2017 in Bermuda and were preceded by the 2015–16 America's Cup World Series. It was won by Emirates Team New Zealand who defeated Artemis Racing in the final. The races were conducted using AC50 yachts, a new class of 50 feet hydrofoiling wingsail catamarans, larger than the AC45F yachts used in the world series and smaller than the AC72 yachts used in 2013. Emirates Team New Zealand went on to compete with defending champions Oracle Team USA in the 2017 America's Cup match.
  The tournament was an expansion of the Louis Vuitton Cup format, with the defender competing in the first round robin stage.
