Mighty Mary was an American International America's Cup Class yacht that was a competitor for the 1995 America's Cup Defender series. The team was part of Bill Koch's America syndicate and featured the sport's first nearly all female crew.
The team was captained by well-known female sailor Dawn Riley and featured sailors such as Leslie Egnot and J. J. Isler.
After establishing a commanding lead, the team narrowly lost to Dennis Connor's Stars & Stripes (who then went on to compete in the 1995 America's Cup) after being overtaken on the last leg.
